Text Based Editing - Sequence Doesn't Match Clips / Sequence incomplete

Transcript for sequence in text window does not match the transcripts generated for the independent clips when viewed source side. The first 10 seconds of transcript of a thirty second clip is missing only on sequence side. Happening for clips throughout sequence. Transcript for sequence is also incomplete by omitting transcripts for individual clips in their entirety. And anything after a few minutes into a 20 minutes sequence is missing.

Yet, as said, the transcripts for individual clips as generated by the text to edit transcript process are complete on the source side. Just not sequence side. 

Static transcribe is also fine. 

Feature is useless as such. 

Clips are Sony MXF from FX9 / FX6. 4k in 1080p 29.97. When usual default channel mapping and modified channel mapping to two track mono (ditching used blank channels). Both used channels have full audio from speaker. Audio is extremely clean and well recorded.
