TCA add-on setting with the WT CJ4

I’ve just got the TCA add-on. I would like to use it to control the WT CJ4. Flaps and spoilers work fine. However I am unable to make the landing gear work. The default setting bind the button 21 (landing gear) to Gear Up and Gear down at the same time. While this configuration works fine with the A320 it doesn’t seem to work with the CJ4.

Any idea what to do? Would 3rd party software such as Spad.next or FSUIPC be of any help to resolve the issue?

Thanks to @sabers431 from the WT CJ4 discord who provides the solution.

Believe it or not! You have to start from the add-on default profile with the default landing gear setting in order for the “landing gear” lever to work. If you just copy manually the default landing gear setting to an existing profile, it won’t work.
