Mixamo Rigging Error?

Not 100% sure what is going on here.  I have a Gen 8 figure from DAZ that has been converted from a figure to an object and uploads to Mixamo to the point of rigging, where it gives me the error "Oops! Place all markers on the character!"


But as you can see from the attached image, they ARE all placed correctly.  Has anyone else encountered this error and have a fix?  Cheers
