In my case, it turned out that it was actually asking me to update the wrong stock entry. i.e. I needed to update my entries for stock A whereas it kept telling me to fix entries for stock B. I had 12 or so entries for A that I needed to fix, but only 1 for stock B that I didn't. So it felt like I was stuck in a loop because it kept showing me the same message ('fix stock B') 5-6 times, which wouldn't have been confusing if it said 'fix stock A' 5-6 times. Once I found the actual entry that was causing the issue, it went away.
