Recently this release was added to MB, using a Discogs import script:
The X is rave/jungle producer Mark McKinley AKA Mark XTC.
So far so good. For some inscrutinable reason, the same release group also shows up at the page of another group called “The X”, i.e. Techno producers Marc Hartman and Ronald Vernes
In fact, if you look into the editing history of the release group (coming from either artist page), you’ll find the script imported it to The X (sometimes showing up as Mark McKinley and sometimes as Marc Hartman and Ronald Vernes )
It is really the same release group with the same MBID, but it doesn’t belong there. I have tried to detach the release group from the misattributed artist, first by setting the artist to The X (Mark McKinley). This results in MB telling me that “The data you have submitted does not make any changes to the data already present.”. Secondly, I tried to merge the release group under the “wrong” X into that under the “right” X. However, MB does not let me add the release group for merging (as they are the same).
So now I am nonplussed. Why does this release show up under the wrong artist? Why can’t I detach it? And how do I fix it? Looks like a bug to me.
