Pioneer CJ-V51 problem menù rotation

[jamex]

Goodness to all,

I have a problem with the Rotation Menu of my CJ-V51 pioneer;

As can be seen from the video that I am attaching the central column and the right column fit at the end of the rotation. I am afraid that this ruins Jukebox so I ask you, please, if there is a way to regulate it
