SBP20 AAFs/XMLs not working in Premiere Pro or Pro Tools

I am working on some animatics in SBP20, and have been building my tracklay of dialogue underneath (48kHz, 24bit, WAV files). A lot of the audio has required speed changes.

I have tried sending AAFs, XMLs, and EDLs to Adobe Premiere Pro and Pro Tools (even trying Final Cut Pro 7), but the speed changes in the audio are not translating across properly.

Can anyone recommend any special tricks or intermediary software that might help retain speed changes in the audio when sending across to Pro Tools/APP etc?

Many thanks!
