I've been seeing recently that if I advance to, say, the recordings tab of the RE of a release with a discID and then I go back, it will only show the first track of the release. By opening the track parser, that still contains the full info, and re-parsing I can continue, but I imagine that's not something normal users will try (and it's a mess anyway ).

It might happen only after parsing a new (corrected) tracklist into the parser - I can't remember right now I'm afraid but will try to make sure later when I edit some more of those
