How to restore a purchased album in iTunes if I accidentally deleted on Apple Music?

I accidentally deleted an entire album on Apple Music I purchased on iTunes while I was on my iPad. When I try to get back on iTunes, if I search the album it is listed as purchased but I can’t download it.

I also noticed that each single songs have the prices on it again instead of the cloud icon.

As you can see on the pics, I can’t click on the purchase icon (here in Italian as “Acquistato”) if I try to restore the entire album, but weirdly I have to buy once again each single songs separately.

The purchased album is still listed on my account purchase history so I don’t understand why I can’t download it again on iTunes?
