Fans turning off when powered

Having an interesting issue since setting up a voron 0 with RatOS 2.1 using an EBB36 toolboard - When the printer is first powered on, the hotend and part cooling fans sit at max speed, and when changing the speed in mainsail, it seems like the fan power is inverted, so at 100% fan speed, the fans turn off, and at 0% fan speed, they are at full speed. Interestingly, this is only happening on the fans connected to the EBB board, and the aux fans plugged into the Manta M4p work as expected Any help would be appreciated
