One analog don't work, when both are linked

[Mellin]

Hi!
I'm new on this forum, so I'm sorry I I use the wrong subforum.

I recently came across a problem with linking a Bluetooth gamepad's analogs.

I use an IPEGA PG - 9055 controller with my android phone with following effects:

What works fine:
-When I link only left analog it works fine
-When I link only right analog it works fine
-When I link left analog and from the right analog only the up movement (not down), "pad1.Z Rotation-" - all works fine
-When I link left analog and from the right analog only the down movement (not up), "pad1.Z Rotation+" - all works fine
-When I link left analog and from the right analog only the left movement (not right), "pad1.Z Axis-" - all works fine
-When I link left analog and from the right analog only the right movement (not left), "pad1.Z Axis+" - all works fine

What doesn't work:
-When I link both left and right analogs - only the right one works (left one seems to not respond)
-When I link left analog fully and left/right movement of right analog ("pad1.Z Axis-" and "pad1.Z Axis+") - the up/down movement of left analog works, and the left/right movement of right analog works, but left/right movement of left doesn't
-Same effect when I link whole left and only up/down movement of right one

I don't have that problem with the same controller and my PC ppsspp.

Is there a way to link both analogs at the same time on android ppsspp?
