PiCade joystick conflicts with SF30 8BitDo Bluetooth Controller

I have 3 x 8BitDo SF30 bluetooth controllers and the first bluetooth controller I switch on conflicts with the in-built joystick meaning that insert coins/pressing start adds two players to the game both of which are controller at the same time by the joystick or the bluetooth controller, any ideas as to why please? Thanks

Hey, welcome! Conflicting joysticks and joystick mapping in general is a sadly common problem. You’ll probably want to do go through your default mappings and make sure they don’t overlap. If there is an automatic way to fix/deconflict buttons, I haven’t found it yet. Just lots of setting and checking.
