Controller auto-fire

hello, I am trying pc version (usually I play on ps4) and experiencing a wierd problem with both my controllers. When I press one of the 2 triggers (r2/l2) it seems like a sort of auto firing is starting and there is nothing I can do to stop it. Both the controllers (one is an xbox nacom the other one is a ps3 sixaxis) works great with any other games on my computer
