Objects showing up in Sheetcam that cant be seen in Inkscape

I have seen this problem happen before but I don’t remember what the causes/fixes were for it. Someone tried to make me a file but it was terrible so I had to redo all of it and after importing the SVG into Sheetcam, and there is tons of extra shapes and whatnot that cannot be seen in Inkscape. Is this a problem with Sheetcam or Inkscape and how do I fix it?

I had that yesterday as well. Some weird squiggly lines. They have their own layer. Easy to disable for this one but I don’t know why

Could you send me a copy of the drawing so I can test it and see what is going on.
