Pressing the Stop Job button (when a job is running) will not just stop the job, but will change the coordinates to what appears to be something random.
It causes a lot of work to have to reset the coordinates again.
How can this be corrected?

Is this with a longboard or super longboard?
This is for the Longboard.
Forgot to mention, I do have the latest version of gSender as well.
OH, and to clarify, I didnāt mean the stop button in the Longboard, I meant the Stop Job button in gSender.
I donāt know whether itās technically the same, I havenāt really tried any of the buttons in the Longboard, while they seem useful, I had never really even tried them.
@NCNC FWIW, I can duplicate your issue running a LB uno in gSender 1.4.11. It does the same thing pressing Pause.
@NCNC Do you still experience this issue on v1.5.3?
I have not seen it happen, Iāll report if it does in the near future as Iām using my CNC frequently again
It happens when I stop the running job but not with the pause. I believe it just loses the Z co ordinate but I have screwed up enough cuts I reset all three. I also wrote down the coordinates one time so far just input them back in instead of going to the auto zero plate - that worked!
Why are you stopping your job? What do you do between stopping and restarting the job? Can you give some more details?
I have never had a situation where, on an Altmill, the position is lost unless the controller is reset. If you are stopping the job to restart the next day (long job) then you better not power the mill down or your position is definitively lost.

I say this respectfully and not in any way rude or condescendingly: I donāt see why even the question, the Stop/Pause buttons are there for a good reason and can and will be used.
There are many valid reasons as to needing to stop a job, even a short one, chief among them safety and the primary reason I use the stop feature if a clamp is too close which was what happened in this instance, I had placed all clamps safely away from the router bit, however I didnāt take into account the space the shoe dust took, which hit a clamp and pressed against the spinning router nut that holds the bit and broke a piece off the shoe dust, having me needing to stop the job before it got worse (I hit both the stop and Oops button at same time).
gwilki replicated this issue with both stop and pause button.
I recently needed to pause a job because a tabbed hole piece broke off the tabs and was loose while the bit was running, you know thatās a big no-no, so I paused the job to remove the loose piece, fortunately I didnāt lose the coordinates, but if it had, it wouldāve been a big setback.
Valuable lesson on thickening tabs for sure, and really only way to learn, valid reason to use pause or stop buttons 
It has been explained to me in the past why the coordinates resetting to previous values is normal and working as designed and having to do with the longboard and not gSender, quite honestly still does not make sense to me, but so long the coordinates are not lost while pressing stop/pause, Iāll call it a win
Of course there is a reason for stop/pause. I myself use them regularly. Itās part of running a CNC mill.
The reason I asked the question is because I wanted to find out under what circumstances the buttons were used and yes, your use is totally as expected/necessary. I wanted to understand what is going on.
There are many reasons why things are happening and sometimes we, the operators, cause issues that we are not aware of and sometimes it helps to look at things with a set of different eyes
Since your experience is with a longboard which I have never used and the situation has been replicated and is possibly as designed (why??), I will leave things up to people who know what they are talking about.
Good luck!
Stop job soft resets the board to reset modals. This is consistent with all other major gcode senders.
If youāre working in another coordinate system youād need to reset back to the correct workspace because the soft reset would reset the board to G54.
