Text based editing only flagging pauses and filler words for the first ten minutes of my clip

When I do text based editing, and go to search for Pauses or Filler words, it Premiere only gives me results for the first 10 minutes or so of my clip. I have to then export the rest of the clip and retranscribe it for Premiere to flag those pauses and filler words. Usually, for an hour long clip, I'll need to export it five or six times  to export the full clip.
