Xinput config sees controller one as 2, 2 as 3 and so on

Just wondering if anyone else has ran into this. I'm using four 8bitdo pro 2 controllers set to xinput mode. I've also got supermodel set to xinput as I try to configure its controls.
For some reason, supermodel is reporting that the first controller is joy2, the second joy3, and so on.
Is this a bug in supermodel? My other emulators see it first player as joy1. Maybe everything else reports it wrong?
