Exporting .dxf from CorelDraw X7, missing fill

Hi everyone,

I'm having problems with exporting from CorelDraw x7 to .dxf or .dwg.

Object that I export are not filled, they only have an outline. I've tried with recombining curves, regrouping, ungrouping and combining, exporting with and without the outline, but I cant seem to get the fill.

Does anyone have an idea how to solve this?
