DS4 recognised but not working

[moosevernel]

Hello people

So i recently downloaded dolphin after playing at my friends and for some reason dolphin recognises my DS4 controller but will not let me configure the buttons. I have googled and browsed but have been unable to come up with a solution. im using dolphin 5.0 and input mapper.

Any help would be greatly appreciated

ps oh and the controller works with everything else ive tried with it.
