Catalog number are optional as sometimes they are not present especially if it’s a digital release. What problem do you specifically have regarding creating a release? The only thing necessary for making a release are the title and artist (the track list can be marked as unknown so it technically counts as optional). Also, seeing as the cover art on their website is different from the one on Amazon, I think you might need to create a separate release for each version. Have you perhaps not created the artist page for Better Life, yet? If so, you should create it (either while or before creating the release) as the artist is necessary for the release unlike the label which is optional and can be left empty.
EDIT: You can read this how-to on adding a release if you’re still having trouble.
EDIT2: Also, why is this in the Picard section?
