Roon doesn’t always show number of versions of a track

Two new covers of all Monk work on the “best-of-2018” lists.
But Roon doesn’t show all the versions I hav in my library.
Crepuscule With Nellie — I have 15 versions, on the new albums Roon shows none, on a Monk album Roon shows 6.

I have checked spelling. One is Tidal, the other a download.

Any suggestions?
