More often than not, games with hardwired dip switches are read at boot time and changing the orientation of the switches is not recommended while the machine is in operation. MAME does not force reset, so such changes with DIP would be best followed by exiting then restarting MAME, or using the SHFIT+F3 which is a HARD RESET, basically stop/start in one step.

I only have MAME64 version 0.207 (official from mamedev.org) and I do not get such an error no matter what the Cabinet switch is set to. MAMEUI, I think by default, saves all previous run information (write config) so if you get a configuration that causes problems, it will continue in that state until you exit MAME and then manually delete your entry in the CFG folder (popeye.cfg) and try again.

Current version 0.215 as well as current Github sources also seem to work fine, so I'm unsure why the UI flavor is having issues. There is a new version expected in just a couple days, perhaps you'd want to pick that up.
