How to reproduce

Sliced the file
Go to Preview
Layer height 90mm
You will see the Tree support but also small supports printed in mid air. There are a few occurrences of this in the particular support
Tree supports are printed with 1 wall loop but eventually it transitions to 2 loops at a certain height.

Actual results

The preview tab shows a small support printed in mid air. The actual printer replicates printing the support in mid air.
2 support loops are printed but 1 loop is selected. 1 loop is printed at the base, but changes to 2 loops at a certain height.

Expected results

No printing supports in mid air, especially when they do not support anything
1 wall support loop = 1 wall support loop and not 2
