Elements get lost after exporting to SVG

[Marvin241503343yhm]

Some Elements of my illustrated Icons get lost after exporting them into .svg
Its always the yellow part of my icons which cannot be seen in svg. If I open the exported svg the yellow part is just gone. 

The png export works fine. 

Any solution? 

Thanks 🙂
