Messiaen messed up merge

Hi!
I found this recording: https://musicbrainz.org/recording/5aea5d30-d7e7-4bef-9d09-990379d76836
that is part of several releases. However, there was a messed up merge at some point because it has two recording dates, that are confirmed by the links for the different releases: https://musicbrainz.org/release/685191d0-243f-4c0c-80fc-77409d87a006 and https://musicbrainz.org/release/186a431a-20b5-4d51-a815-7d0aa5ae65d7 . Any idea on how to deal with this efficiently? I don’t have all the different releases, only some of them.

It being DG, you might be able to find all of the releases (with recording info) on their website.
