hey Tango,
What you can do is download a preset hotas profile. i use those key set up from mustang :

may be a reset of your keying (with those .lua files) and your trim just assigned to your stick would help?
BTW If you want to check your DCS version go to MISSION EDITOR then MISC then CREDIT and you will have the full version number ;)
hope it will help!
