I’m not sure if there’s already an appropriate topic open for such an issue but nevertheless I thought it’s worth reporting.
Edit #95566162 - Merge releases
Based on the date of me entered this edit (2022-12-28) and that no ‘No’ votes were cast, it should have been closed a week ago, yet it’s status is still stuck at open, hanging at the bottom of my open edits’ list.
Have seen that before. May just be easier to do a fresh edit and cancel the old one. Something has had a hiccup…
You are merging an old 2007 release into a newer 2022 one. Maybe there would be less of a hiccup in the other direction? The old release is glued in to the system too hard and don’t wanna let go. 
It’s a known issue, but fortunately it has a workaround: (temporarily) deleting the annotation on the target release.
What salo.rock said. I just move the annotation from the target to the source and it works.
