Is your feature request related to a problem? Please describe.

I use layer height of 0.15mm but in Height Range Modifier, I have: Start at height 0, Stop at height 0.2 and Layer height 0.2 with Perimeter set to 1. After printing, I noticed that there is a groove line on the first layer. When checking in PS 2.5, I found that although External Perimeters were printed in the first layer at 0.2mm, Perimeter was not printed even I specified that there is one perimeter in the first layer via the Height Range Modifier. From the photo, you see an empty line between an External Perimeter and a line of Support material. At 0.35mm, I started seeing several perimeters per layer. Is there an option to make both the Perimeter and External Perimeter show up in the first layer?

I'm not sure I fully understand, do you have a 3MF you could attach to reproduce this?
