Watchout for Bools/Lists and UI to UI commands

Hi,
this Softare turned out amazing in the first steps, when you only want to little tinkering. But the moment you want to do basic things you run into bugs which are not solvable. No reaction from the developer aswell. But at the same time he posts “working on 2.8”.
Please fix the Bugs or describe the error im making for the last weeks.

i attached a simple function (incl. setup so you can try it at home).
Something ist wrong with exit functions and/or lists.

The Arm Drums Action should arm a group of tracks i defined. One Press for Arm, next press for unarm. But instead it just doesnt run all the way through and stops working then completly.

Im really pissed at the moment and i would be happy to give the first person to help me out 100 bucks on paypal.
