FCPXML freezes in NLE from Resolve

This has happened to me pretty much everytime. I CC in Resolve, Render with the "Round trip to FCPX" setting. I then bring in the XML into FCPX and the sequence is just freeze frames, but it brings in the color corrected shots into the Event fine. So everytime I have to reassemble the whole cut. I have taken out all speed changes and freeze frames and even Graphics but it still keeps happening. Any ideas?

Are the clips your render in Resolve freeze frames when p,aged back in Resolve? What are the rendered codec details? Does the same thing occur with 9,0.1.1?
