MC 6 --> AAF --> Davinci Resolve problem

the AAF roundtrip works with my 1080p timelines. but now i have a PAL 25p SD project and i cant get it into resolve.

when loading the PAL 25p AAF in resolve, it shows me 1920x1080 ?! The "Automatically set project settings" is activated. After clicking OKAY to load the AAF and setting the file path to the Avid MX folder, resolve does not find the files. Changing the settings manually to PAL SD in the AAF import dialogue (or at the very start in the resolve project settings) doesnt help.
importing the clips manually does not work either, since resolve does not even see the clips in the avid MXF folder. it shows only the 1080p mxf files..

using different codecs in the MC does not help either. its the same in DV25, 50, or MXF ProRes

i tried the roundtrip with FCP and XML - and everything works fine either in 1080p or in PAL SD. but i have to do this on the MC 6

any suggestions? thanks
