Hi Ben,
FYI, I am a fellow user like yourself.
The Discography section can be problematic if Roon doesn’t see the streaming version as the same version that is in your library.
The weird and confusing dichotomy between the function and purpose of Overview and Discography have existed since the sections debuted with 1.8 and there have been equivalency issues (between local library and cloud source) with Discography since it launched.
Over the years bugs have been fixed and I think some are still on bug list (like this thread, not saying it is the same issue as yours.)
Suggestion
Chicago. You will notice that Roon is choosing the 50th anniversary version of CTA to display in Discography which you don’t have and doesn’t have a library icon. This suggests to me that Roon is not matching your library albums as being the same versions as the chosen edition in the cloud based services.
What do you see if you click the library icon under Discography (shown below). Does your version appear?
