Seat adjustment not solid?

Hi there,

I have the emody logitech one and the seat you can move forwarward and backward with the two hendels at the front side. But ive noticed that the setting seems te retract itself to where i want it to be. It is good for a few days but then i notice that the seat has retracted like 3 clicks.

Does anyone recognize this and/or knows why this happends?

Thanks!
