If your SVG file is not working correctly inside the Plasfy editor please first open the SVG inside the SVGOMG tool here:
https://jakearchibald.github.io/svgomg/


After doing so, please then export the SVG and try re-importing the SVG into our editor. 


If this does not work please send the SVG file to our support team and we can locate the issue with the SVG file or advise you on how to resolve the issue.
