Fx channel selector does not work on deck 2

I have been using the Windows Day Pro app and pairing it with my DDJ FLX4 controller. When i have a song playing on deck 2 and switch the FX channel selector to deck 2 and turn on the Fx, the Fx does not apply to deck 2. On the other hand when deck 1 is selected, it works and same for 1&2 (1 has fx applied to it but not). I’m going crazy pls help🥲
