EC135 V5 MacBook Pro can’t move 3 position switch. Start switch not moveable.

 Hello. I have the EC135 V5 on X plane 12 and certain switches are able to mouse click on and off but others that are 3 position (Master battery) only show small arrows. I have tried to click, scroll, click hold scroll etc but nothing works. Also the Engine start switches are showing as not moveable ( no green box around) I’ve been trying to find key activation but not able to find. can someone advise. hopefully a simple solution. thank you  

Hi, said earlier also in an other post that in VR, in XP12 (not in XP11), very difficult to have the good arrow to manipulate the engine switches. Have to spend each time 1 or 2 minutes to move the mouse in millimiters to have the upper arrow fixed and usable.
Was waiting for assigments to hardware buttons but waiting for months now to have a new update.
Hope we'll have a good answer from rotorsim
