Hi folks,
I’m trying to correct my release which is a single, naturally containing one track. When I renamed the track to the correct name it ended up creating a new medium. It’s meant to just have 1. Nice - isolaet (2:14) on it. Whenever I try to delete the incorrect mediums nothing happens.
Here’s a link: Release “Nice” by isolaet - MusicBrainz
Any suggestions?
Welcome to MusicBrainz 
Things are happening, but most actions require a review period before they are applied, which is generally 7 calendar days. This doc might provide some answers: Introduction to Voting - MusicBrainz
You can see the status of all the open edits for this release here: Edits for Nice - MusicBrainz
Please note that most of these edits will fail when one or more are applied as the data will have changed when they are either naturally accepted, or are approved.
Just as an aside, I know it may seem silly, but edit notes are pivotal in helping voters review said edits. Putting “I am the artist” is acceptable, but adding a link such as the relevant BandCamp (or other storefront) helps folks understand why an edit is occurring.
