Machine size settings not saved in 1.0.3

I’ve run across another issue in gSender settings. I can not get the machine size settings to be remembered permanently. They are lost every time I exit the program. I also do not see the saving settings message when changing the settings. They are also not saved when other settings are. As far as I know, this started with version 1.0.3.

I stumbled on this when I reset all settings back to the defaults while trying to validate other settings changes.
