Issue with game testing

[MercilessWays]

I am currently testing a pre alpha version of a game and tried this to connect my ps4 controller. I can navigate through the menu and movement in game is great. However, once I fire an automatic weapon it runs away and continues to fire until the mag is empty. It them proceeds to reload and empty the next and so on and so on. The only way around is to use a single fire weapon which run off is impossible. Any ideas? Also this does not happen using an XBox One controller.
