A couple of my recently imported shows were incorrectly matched, so I used the "Fix Incorrect Match" feature to fix them. I have used this in the past with success, but this time it only fixed the episode matches. The show metadata remains incorrect (art, title, description, etc).
Of note, when I have used this feature in the past, I would see the episodes disappearing from the show page in real-time (as they are moved to the page for the different/correct show). This is no longer happening, perhaps the episode metadata is being updated but the episodes are still being associated with the original/incorrect show?
