EDIT: HOLD THE ADDITION NeroA.
There is a possibility that your Release is the one that is in the database already and that the release was unintentionally “hijacked”, with the best intentions, by editors with the 1C version.
Hi NeroA.
Your Release has different CoverArt.
This makes it a different Release.
Please add it.
Releases are defined as having unique CoverArt.
So having a Release for 0777 7 89599 2 2 and a release for 1C 0777 7 89599 2 2 is good.
Looking at Release f1bba495-27a8-47e6-b6f7-fb646ce85ac1
It was initially entered into database without a catalogue number.
It then had a Disc ID added 2006-03-30

Then Cat Number entered as 0777 7 89599 2 2 on 2007-08-22
https://musicbrainz.org/edit/7400578
Then from 2013-04-17 (or even earlier at Amazon?) it is getting 1C CoverArt.

On 2016-08-07 (I think, in some mysterious process that is recorded only at another Release) it got another Disc ID in https://musicbrainz.org/edit/40106973
Then in 2018-11-26 it gets 1C Catalogue Number.

It appears that two separate Releases have been mixed up with each other.
NeroA, which Disc ID does your CD have?
(See DiscID)
@reosarevok and others;
How better to disentangle these releases?
