retroid pocket 4 pro left joystick not working

[José Alejandro Castro]

Hello I am trying to use the emulator and when I try to config the buttons of the controller/new, the left joystick is not working.

It works perfect as per other platforms but not with mupen64

If I go to controller diagnostics and I use the left joystick it says Device: 4(mtk-tpd) where the right joystick which actually works puts; Device: 5(Retroid Pocket Controller).

I don't know how to fix that
