Custom Tags/Search Not Working

I have 46 albums I custom tagged as “80s” or “80’s” and Roon only finds about 24 of them after searching multiple times. If I search the exact name of the album, “Sounds of the Eighties” then they all come up. Why is that? Tagging and searching do not seem to work. I am finding this on other custom tags as well.

Now I see them only under “Tags” but not under search? Why is that? Can’t the search function also find tags? Why is this such a cumbersome app for some much $$$?
