Unable to execute imported SVG in fluxStudio 1.2.4


Hi there,
the laser is nicely engraving and cutting, as long as the design is made in fluxStudio (e.g text, lines etc). But unfortunately, the import of SVG files (e.g. from InkScape) is not resulting in any activity, it predicts a process time of 1 second and nothing happens at all. So, I consider the hardware to be OK, but a software bug.
(Beambox OS 1.8.5)
Please help me with this issue, thanks
