How can I fix CD import issues in iTunes?

I am recently having an issue with 2-cds for which I've imported into my iTunes library. They both show up in my recently added on my laptop (MacBook Air, 8GB with Apple M1 chip) but when I go to sync, 1-cd syncs but won't play on my iPhone 13 Pro Max 1TB and the other cd doesn't even sync to my phone at all. Usually when I sync, there are 5 steps taken in that process, however I'm getting a lot of just 4, not sure if that means anything but is anyone suffering like me? Not sure if this means anything but my music library alone is 283.92GB out of 1TB. Help!
