Im setting up prosim 737 max cargo fire panel for the det select fwd and aft A, Both, B switches. I set the commands in mobiflight the same way for all the switches. Mobiflight registers each switch as I turn to the appropriate position. When I turned the FWD from both to B, back to Norm then to A it wont switch to the A position then the switch no longer registers in prosim. same thing goes for the AFT side. I dont have settings on the release part of the config.
Here are some screenshots with the configuration. This is MSFS2020 with latest (todays update) of Mobiflight and Prosim 737 Max Software in 30 minute eval.
