circuits.io files not processed by Fusion PCB

Hi all,

I am using the online PCB design site circuits io, which is a wonderful way of easily creating PCBs. However, I the files I have uploaded for manufacturing by Fusion fail. I have had different error messages. The current one is:
Your file have two ourline, we are not sure which one needed, please correct your file ,then re-upload it to us.

The board does seem fine in gerbv and I’m not sure how to address the issue. Can anyone point out how to fix the files.

Thanks,

Ronald
