Errors on split clips with cross dissolves. when importing AAF from Avid Media Composer.

AAF export from Avid Media Composer of a sequence that has split edits in the audio tracks and cross dissolves.

For some reason the Premiere Pro is reading the Timecode wrong either side of the split and repeating frames so the split edits are not correct.

If I remove the cross dissolves in Avid first then the sequence displays correctly. 

Is this a bug? Or a limitation? I am not sure I have seen this before in the past.
