Gumball Cplane issue

I am a bit desperate.

Since recently, my gumball extrudes et rotates slightly off Cplane
Which makes all of my planes tilted.
Whereas when i rotate, move or extrude without the Gumball, it makes a perfectly fine planar rectangle.
Would you be able to help me understand what the problem might be?

Thank you


What is your gumball alignment set to ??
