Bleeding to Death

Hi - seems like a really stupid Question - but I cant figure out the way how I should use Bandades/Bandages. All I can select with my controller (I play on PC with controller) is to drop them, or to reed Information about them. In the Tutorial it just sais you pick up one Bandage in the Inventory and put it on the bleeding bodypart. But I cant pick it up…no drag and drop…no button works… Please Help! Made it without Knowledge of fighting threw 3 fights and dont wanna die now.

I have same problem, can’t use bandages when bleeding. Playing on PC with keyboard.
