Export your track as WAV, use Sound Devices Wae Agent and change the sample rate to 47952. Import with audio settings to do pullup/pulldown. That should slow it down the additional .1%.
Imported files do not have the TAPE MOB needed to generate an EDL in the first place, regardless of which field you use as source. This is something that is being looked into.
You can make your first edit in the timeline all the audio tracks – or perhas use “audio follow video” for the 4 sync tracks to the video and just lay down audio onlu 1-8 to sequence tracks 5-13.
