Wants to to pay again for song bundles Ive already purchased.

Upgraded from an iPhone 5S to a new 6S and redownloaded this game. Bummed to find that although the music store shows some of the bundles are already purchased it wont actually let me redownload them without paying for them again. Why show an "already purchased/redownload" button only to ask me to pay again when I select it?!
