Missing Walls and Surfaces

[FormulaNerd3D]

I was about to print this filament swatch and noticed that there were walls missing and some of the surfaces on various layers were also missing. I first saw this issue on the stable 2.1.1 and I tried adjusting my settings and nothing seemed to work. I then downloaded the most recent nightly build of 2.2.0 and still saw the issue. I did not have this issue last night when slicing a similar swatch.

Here is the first layer. Most notably you can see the missing walls (I had it set to 3 perimeters) on the five holes and the hexagon cut-out.

Here is the top most layer and you can see the missing/incomplete walls in the diagonals in the top right. You can see there is missing surface and walls in some the steps of the hexagon.

I have also include a ZIP file with both the 3MF project file and the STL.
