I have a svg I want to flip then cut/engrave,

I have a svg I want to flip then cut/engrave, I can do it in inkscape however when i add the mirrored file into laserweb, some of the objects lose their fill. Even happens if I mirror then un-mirror the file and save it, it still looses fill when opened in laserweb 4.0.991. There must be something simple I am missing here. Thoughts?
Fills work fine If I dont modify the file before importing in to laseweb.

try clicking stroke to path after flipping, that sometimes works for me on similar glitches.
