The v2 adapter that shipped with my ANSI PBP in January had a similar issue; with some pressure on the back plate while using it, the right-click of the touchpad would get stuck. I cut the adapter PCB in an appropriate place and it works fine now. I honestly just used a pair of hobby scissors - the PCB is thin enough to just cut it like it. No issues whatshoever, the board got a little bent front the pressure but it's thin enough to bend back into proper shape.
Works like a charm!
