Feed Override not working for me

I use gSender (Latest) to control a home made CNC Router with MKS DLC32 V2 board controlling Nema 23 Stepper Motors via Seperate drivers.
All has worked well for over 1-1/2 years.
I managed to blow up a FET on the board so had to change it out. I reloaded the configuration files and the gSender config I had saved.

All is up and working perfectly again except for one thing, when I adjust the feed override through the gSender GUI the % slide moves up or down but the actual feed rate does not change either on the GUI or physically on the machine.

It was working fine with the old board so I think maybe a parameter may not be set correctly.

Looking for any suggestions, thanks in advance.
