Longer lk5pro clicking sound filament feed.

I have this clicking sound with the filament feed, when the little wheel turns back a little every now and then, where the filament is going into the tube.What is this and how to solve it?Thanks in advance

When the wheel turns back it is usually retracting the filament as per the slicer retraction settings.
It is perfectly normal.

Yes, i thought so too, but it goes with a click, not allways. Maybe slipping or something??
