XDJ-RR pre-cueing feedback issues

When I turn on the setting to use my XDJ-RR controller for pre-cueing I get this weird feedback loop in the music that overloads and forces me to close the app to make it stop.

Any idea how to fix this?

I’m wondering if it’s because the XDJ-RR is 2-channel, but loads of other controllers are as well?

Resolved this… had Rekordbox open in the background. Oops!
