ITunes making me buy pre-ordered album again?

I preordered an album, but now that it’s released it’s making me pay again? I had bought three songs from the album before I preordered it (since they released early) and I still own those, but now it says ‘complete your album’ whereas it used to say ‘preordered’ and every song except for the three I bought early now has a price next to it, and telling me I have to pay for them a second time. The album was ok orchestra by ajr if that helps.
