SVG Geometry inverting when selecting "Use surface"

TL;DR Clicking “Use Surface” inverts SVG geometry so previously negative space is positive and vice versa. Have tried multiple SVG files made by me and others, all have same behaviour.

Hi all, just trying to get my head around this issue while also working out the best way to explain the issue.

I am trying to create a cylinder which has several designs on the outside using SVGs which I have done several times in the past. However, I am encountering an issue that appears when clicking “Use surface” to wrap the SVG to the surface of the root object.

To walk through the process so far, I am right clicking the object I want to add an SVG to and selecting Add Part → SVG. This is what it looks like after doing so and resizing as desired:

However, after clicking “Use Surface” to wrap the SVG to the object, the positive portion of the geometry becomes negative space, and the previously negative space of the bounding box of the SVG becomes embossed on the surface, as pictured below:

I have two other SVGs already applied to the object in the same way, and can remove and reapply them just fine without this issue cropping up. I have tried performing a mesh boolean so the object is one piece without the SVGs still editable to no avail. I have also tried other SVGs (I have 5 total runes I am trying to add) and they all seem to have this same issue when “Use surface” is clicked. Fixing the model in slicer and in 3d model viewer (w10) has not changed anything, and I have also remade the SVGs myself by redrawing the symbols and using an image to SVG converter, and the behaviour remains the same.

I hope this makes any sense, and appreciate very much any attempts to help!
