I had a segment waitlisted for J but the flight got a minor schedule change that included a flight number change and now the whole thing is messed up. Now it no longer says I'm waitlisted for a fare class, just that I'm waitlisted for a flight. It also has the previous flight number which no longer exists and says I should call to get a segment confirmed. Previously, it just had 3 segments listed and the segment I was waitlisted for an upgrade on had a note in its box saying I was waitlisted for I (from X). I attached a screenshot.
