Hairworks export error

Hello everyone,
When I export the hairworks apx file in maya , it gives me the error that 566 out of 1280 fur strands share mesh vertices with other lines. I groomed the guild curves in xgen . So the curves were placed on the poly faces not the points So please help me. Is there anyway to figure it out, and allowed the guild curves on the face can be exported correctly. I need your help. Thank you so much!!!
