Stereoscopic AAF roundtrip

Hi everybody.

I would like to make a roundtrip via AAF between Avid Media Composer 6 and DaVinci Resolve. I have tested with 2D project and in that case it works very well, but in stereoscopic project it doesn't work:
When I import the AAF in Resolve I have the following error message:
"Effect StereoVideoCombiner is not supported, plain clips will be imported only"
So it seems that MC6 creates AAF that refers to stereoscopic clips but not to the original 2D medias. I have tried to switch the stereoscopic selector to the difference possibilities : Left only, Right only, Full, Leading eye and also off and in all case I have exactly the same message error.
Creating an EDL via EDL manager works well, in that case I could select the eye I would like to have in it but I didn't find the same way in AAF export.

I have contact the tech support of DaVinci but they have no ideas. I have tested this with Resolve 8.2 and Resolve 9.

Any ideas are welcome.
