I have found two releases where it looks like one is an unfinished attempt to enter the data.
This release entry contains 19 tracks and some metadata: https://musicbrainz.org/release/f72cdee5-47fd-4d17-a4ed-76bbc4e91ff6
This release entry contains 17 tracks and no metadata (even no track lengths): https://musicbrainz.org/release/5d853fa8-806d-4005-bbf7-eb2d91adb928
The first 17 tracks are the same in both releases, but the last 2 tracks from the first release are missing in the second one.
It looks to me like somebody started to enter the second release, but stopped before entering all tracks.
Is it appropriate to merge these releases and related release groups?
