Line Divisions Issue

I sent my .step file in to get a quote from PCBWAY, and they sent this back to me. Anybody know what they mean, and how to fix it?

I managed to fix the lines within the circular holes by redrawing the sketch, but the shaped holes and the outside perimiter of the part are still having issues.
