ULX - double clicking

running into double clicking on the new ulx (batch 2). while it doesn't happen 'often' i play fps shooters and i'll notice it like once every 2-3min as it's painfully obvious i completely let go and it still manages to get another shot off say while playing a tac shooter.

anyone have any suggestions on how to fix? ideally not trying to send back for repair or anything of the sort.
