In that release, I could see that most recording were linked to works as " — ????".
Which means the "ended" checkbox was checked.
But in the relationship editor, relationships with "ended" checbox checked do not visually differ from relationships with that unchecked.
Except if you open all popups the one after the other to see the checkbox.

You can't see it any more on that release (autoedits) but just check this box anywhere to see.

I think we used to see either ( — ????) or (ended) at some point...
