Is there an existing issue for this problem?

Additional system information

I noticed that when trying to tweak the infill overlap for the top layer of my print, nothing happened. However, adjusting the normal infill overlap also modified the top layer. The problem is that I want a different value between the top layer and the regular infill. I know that I'm not mixing the two up, because the internal infill is purple and the top infill is red in the preview window. Adjusting the regular infill overlap is the only thing that affects both.

Printer

N/A

How to reproduce

Add a print, adjust infill until a change occurs; see the change also happen on the top layer. Try to adjust similar settings for the top infill and see nothing happen. In this case, it's the base of a retraction tower.

Actual results

Wrong infill setting for top layer.

Expected results

Top infill setting should be independent.
