APE E-Trigger

I have a question.  I have had my new APE board for a few weeks now, and am starting to see little problems.  When I am just messing with the trigger and the gun isn't gased up, sometimes the trigger won't make the sear engage.  I hear the electrical "click," but the little rod doesn't go up and hit the sear.  I'm not quite sure why it does this, but when it does, it doesn't want to work right for a while.  Also, I just noticed a minute ago that it kept reverting back to the semi-auto mode after a few seconds of not pulling the trigger.  Both of these small problems are kind of weird.  I have yet to actually shoot the gun with this new set up so it might be perfect when it is actually gased up, but I won't know for a few days anyway.  Any help or insight would be appreciated.
