Can´t add a disc ID to an existing release


I bought a 3 CD set, when I insert it it indicated the Disc IDs are not found and offers to submit. When submitting I was able to add CDs 1 & 3 to an existing release:

However when I insert CD2 and follow the same steps only CD1 and CD3 ToC are offered as matches. How can I add the CD2 Disk ID to the corresponding CD in the same release?


Nevermind, Disc#2 was missing a track so it didn´ t match.
