Top layers not correct infill

Hey,

I have a question about the correct setting of printer or slicr3, the objects are just fine printed, the top layers are not that nice. It seems that he does not close the holes correctly. As an example see the picture, weird because the right side is better than the left side. If I move the object more to the right or more to the left, again slice then that does not matter. Which settings can I best look after? I print with K8200, PLA, 2.8mm.




Also, when i turn it around voor 90 degrees its doesnt matter, it always the left side from the object (not the bed) thats not looking fine
