Small circles created in slicer from last bottom to top

I have downloaded and sliced the following model:

Slice is using Arachne and 20% cross hatch infill.

My problem is that small circles are created while slicing and they are built up to the top surface. I want a homogeneous top surface (no ironing).
Tried with Classic wall generator setting, but have the same outcome.

This behavior is not only showing up only on this model but on others as well.
