TX15 Switches not recognized

[Hozon]

I'm not having any luck configuring my switches. I get an error message "assigning a key and switch to engine off is not allowed"

Also, I can't get the sim to go full screen. Sure is a lotta bugs compared to my other sims

Is there anyway to fix this?

When you configure engine on/off to a switch, remove the on/off-setting in the keyboard settings first.
