Hello! i have two problems with my controller on the pc Version of the game

i connected the controller with cable and Bluetooth but its all the same

1) if i press L2 to lock on a target my Character automaticly makes an attack. and i dont press any attack key... with keyboard locking on an Enemy works fine. (no auto attack after locking on)

2) the on screen keyboard from the ps4 controller always pops up and i cant see half of the screen until i click it away. After a few seconds it pops up again. i cant find how to disable it

are there any pc gamers with ps4 controllers out there to help me?
