How to resolve iTunes syncing issues?

IIm trying to sync three compilation albums onto my iPhone 6. Every other compilation album I have syncs perfectly fine, but iTunes won't allow these three to sync. I've restarted iTunes, my phone, and my computer multiple times. I've tried adding them manually and syncing them automatically. I've tried over Wi-Fi and with a USB cord. Nothing I do will get these albums onto my phone.

Apple Store's Staff at the Genius Bar would know more.
