Issues with Lightbox Maker

First time posting here, running into an issue where I upload an SVG file I made in Adobe Illustrator into Lightbox and while for the most part it works, there’s some weird things going on with some of the art, where it seems as though it hadn’t cut through properly, particularly the white parts of the artwork that should of cut through the black outline. While in the slicer it doesn’t seem to be causing any problems,splitting it to parts reveals that those black outline wasn’t properly booleaned/cut. And I’m worried that this might be a future issue for me that I have to fix if future lightboxes.

Press slice
What happens?

3d objects are allowed to have overlapping geometry, the slicer is the thing that’s supposed to figure it out.
