Hi, welcome to the forum!
Have you played around with different layout elements found in the arrange panels dialogue (next to the search box)? That left panel can be changed or removed.
Also, it sounds like you should look at whether your compilation albums, like Black Panther, are tagged with a consistent album artist (usually various artists, but it can be whatever you want). Then also make sure you're sorting /grouping by album artist, not just artist. Assuming you want it all to be treated as one album.
