Dualshock 4 Bindings reset after each reconnection

[Swift.]

I'm currently using a Dualshock 4 controller to connect to my PC via bluetooth, and it works a dream. No problem binding what I need bound in DCS, but whenever I turn off the controller and reconnect it, the controller will initialise without the bindings I set up previously.

Has anyone managed to stop DCS from doing this or do I just need to get good at setting up bindings quickly!
