hhmm i see, if thats the issue you can try to outline the stroke, i never used inkspace but i am sure this is possible as you can do it in another vector programs.
and next time don't forget to export to multiple editable extension such as .eps or .pdf
I might stop using Inkscape altogether it has all sorts of weird glitches.
Ofc I will.
In Inkscape doing so will remove the fill and only the stroke shall remain as a path.
