Problem modding my Qanba Q4 RAF

Hey guys,
I recently just bought a Qanba Q4 RAF (rebranded as Bigben) and I wanted to mod the joystick.
Since I already had a modded Mayflash F300 with a Crown CWL-309MJ-KMS-ST25 Joystick, I wanted to swap out the joysticks.

However I encoutered a really weird problem : when I plugged my Crown joystick in the Q4 Raf, only the up switch was inputted correctly.
The other directions didn’t work at all except whenever I would input a diagonal. The same thing was happening with the Q4RAF joystick in my Mayflash F300.
And whenever I would put back the joystick in their original place, it would work perfectly

What’s the problem ? It’s the first time I see that problem and I have no clue where it could come from. Is it because the stick is rebranded by bigben ?

Thanks in advance

I would say you have to plug the cord the other around (180°)
