iTunes Syncing incorrectly..

Basically i have Apple Music, but i want to Sync Mixtapes onto my phone. I did and basically, it shows tons of the Tape Artwork as one album multiple times with one song in each, also some of the artwork changes.

I just want a Clean Library i have 600+ songs and it's been sooo difficult. Anyway to organize it? iTunes is so dumb because I made sure all the files match the Album Name, Artist, EVERYTHING NOTHING WORKS... ITS SO FRUSTRATING I LOST MY GOOD LIBRARY OF MIXTAPES TRYING TO ADD MORE.

I WANTED NO CEILINGS BUT I LOST EVERY TAPE AND NOW MY LIBRARY IS SO UNORGANIZED AND UGLY smh.
