I experienced this bug 2 times now, both times when I was adding a release and re-using an already existing recording. The second time it happened by adding the following release: https://beta.musicbrainz.org/release/5f1ace23-3f4f-4eba-b00a-586d15c43a3e . During the editing when I was on the Recordings page, I selected the first recording in the list (which is https://beta.musicbrainz.org/recording/0e28d181-bf4d-4357-9eae-5cdad63d3a95), then pressed enter. After adding the release, I can see that the recording used for the track is actually not the first recording that I selected from the list, but the last recording from the list (https://beta.musicbrainz.org/recording/00454b61-5818-458a-8d0d-1969c1fc76cd). Additionally, when I go to edit release and select the correct recording and proceed with the edit, the Edit Note tab tells me that I haven't made any changes (I think the changes briefly flash for a split second there). This issue is only present on the beta site.
