Importing AAF - all WAVs have wrong FPS

Hi,

I need to import AAF from Premiere which almost works fine. The sequence looks OK and the source files are offline in the bin and the filenames look correct. 

But all WAV files are in 29.97 FPS which means they differ in length and it is not possible to batch re-import them to make them not offline. Is there any chance to change this wrong metadata and batch import them?

So far I use a workaround with another project at 29.97 fps but it seems to me not ideal to have media with 29.97 fps in all 25fps project.

Thanks a lot.
