Database problem

I am trying to add an artist to the database, but she does not appear. Even if I change the artist name in the tags she does not appear? I tried “adding” as well as “rebuild” for the database but no luck.
I have 879 artists, 927 albums and 10647 tracks, is there a maximum?

If I remove the current source and add it again, will the database in Volumio also completely be renewed?

Any other suggestions? Does Volumio also store database info on the SSD, I have 120gb, can it be full?
