Refuses to scrobble perfectly tagged Mahler 16cd box set to last.fm

Everything else in my library scrobbles perfectly to last.fm, however anything to do with this Mahler box set is simply ignored.

The set in question is:

Barcode (Text): 5 099960 898524
Barcode (String): 5099960898524
Label Code: LC 06646
Other (SPARS Codes): ADD/DDD

File format is flac and tagged perfectly according to musicbrainz using the above barcode string.

Inside Roon the box-set is identified perfectly and split correctly into 16 discs with album art and other informational metadata, however any playback related to any song inside this set is ignored on last.fm.

Manual searching the Box set on last.fm yields a perfect match, so they have the data too…

Please help sort out this annoying issue, losing out on hours of scrobbles per day is infuriating.

Much appreciated

Ok solved, I solved this by selecting another album version of the release under edit album view and then after saving reverting back to the original. This back and forth somehow resolved the glitch that would prevent this albumn from scrobbeling

@mike, It would be good to take a look at this anyways.

Lets get a support package from @protskrog, then you guys can try to reproduce this using the collection dump in there.
