Mayflash sensor/Wiimote problem

I am attempting to use the Mayflash sensor bar and a real Wiimote with the Dolphin core. I already have an Xbox One Controller connected through bluetooth to my PC. When I try to sync the Wiimote, it always registers as controller number 2. I can’t figure out how to set it as the main controller for Dolphin.

Anyone come across this or have a solution?

Thanks.
