Was there a fix for this as I seem to be having a simular issue.
When using the f16 a push and release on the A-A A-G IFF and all the others there it will register like a push in the touch and release.
The Ch47 does the same on the CDU. it registers 2 button presses, one on touch one on release.
The AH64 KU doesn't seem to have the same issue and works correctly
