MCG Brake axis activates Manvr buttons

[ags]

Hi! I have GF MCG Pro on an mk3 base via black box, a 10cm extender, tried 1.989 and 1.986 firmwares.
Brake lever is set to have buttons (29, 30, 31).
However, when I pull, it activates button 15 (manvr right), and on return, 16 (manvr down).

Suggestions?

Joystick has to be reset to default after flashing and before calibrating. After that don't forget to check A2B (axes to buttons) box in the Profile/Axes/Axes to buttons panel and hit Set button to save settings.
