307 Sunroof problem

My vehicle 307 XR BVA 2003 HB. I have a Sunroof in my vehicle BUT;

The Sunroof cascade button sometimes sticks and either opens or closes two or three stages. The first time I picked up the car, when I pressed the switch control button, it closed both the windows and the sunroof, now it just closes the windows.

Does anyone have the same or similar problem and fix the problem?

I would be glad if you could help.
