[BUG] Right stick is pointing to the upper right corner

[FewixWasRight]

Describe the bug
When using non official joycons, right joycon's stick is constantly pointing to the upper right corner in the idle state. When pressing stick downwards, it switches to pointing to the right. Every other stick position does nothing, so in every position other that downwards the stick is pointing to the corner.

Testing them in any emulator hasn't shown this issue: in every emulator i've tested (without using betterjoy), both sticks are working just fine. Xjoy has the same problem too. Also, i've tried somebody's betterjoy build where one can change calibration method, and it worked, but it opened another can of worms: joycons became two separate pro controllers and nothing seemed to help with that (although, both joycons were working as expected. Both sticks were behaving normally). So, this all leads me to believe that the issue is with calibration and/or joycon detection.

Expected behavior
Stick staying at the center when idling and moving accordingly to physical stick movement.

Controller (please complete the following information):

• Type: split non official joycons
• Connection: Bluetooth

Edit: i've specified some moments that may be needed for deeper understanding of the problem
