It seems that the release merge edit that marked all those recordings as pending, has not freed them from this status.
Are you less lazy than me to create a Jira bug ticket?
By the way, I think you did notice that disc 1 tracks were all linked to wrong recordings.
You shouldn’t have any issues if you try to fix it now.
But should we leave this release in the current state, for the sake of debugging the bug? 
I never remember the Discourse @ mention for the MB dev team…
