Missing artwork iTunes 12.7

I just upgraded to iTunes 12.7 and I lost most of my album artwork in the Library album view. But if I click on an album thats not showing artwork, and than go to album info>artwork its there. Than if I click out and the artwork shows back up. My problems is I have over 7000 albums in my iTunes. Thats a pretty long time to go to each one over and over again.
