Joystick problem

[kolior4eto97]

Hello. Recently I bought a new controller - Marvo GT-014. I've been playing a couple of FIFA 19 games and everything was fine. I opened the Settings page in Prepar3d so I could sort out some buttons. I noticed that some of the buttons on the joystick don't work(probably with the sim because it has been working on others game fine). For example my left rubber, my L2 and R2 buttons and some others. To sum it up half of the things work, and the other half - doesn't. Also i will be really grateful if someone shows me how to calibrate my other rubber as well, as it gets some random moves in the sim every now and then. Thanks in advance!
