For some reason, sorting by number tracks is (half-) broken, as illustrated in these screenshots.
The first couple (of hundred?) entries are correct, then the order seems to become random.
Also, albums with no tracks (zero tracks, usually those with incomplete information) are not sorted together. Weeding these out is my Motivation for sorting by number or tracks, btw.
Is this a known bug?
Cheers, Lorenz
UPDATE: I just tried replicating this, but now it seems to work!
I did make some changes to my collection in the meantime though (such as re-adding albums with no tracks -but linked to core- via their barcode)
So maybe this was just a glitch of sorts?
We just had one of our programmers here look at it but we were not able to reproduce it and were about to ask if it is still happening for you.
Iām curious though if you do get it again: let us know please 
Many thanks for looking into it! 
Will report back here in case it happens, thank you.
