Item "no longer available for purchase" is still available

The doujin/CG Set "A Story About Boys Who Were Being Used to Sate the Sexual Desires of Highschool Girls Whose Sex Drive Went Crazy" is marked as "no longer available for purchase" but still has a price and "Buy" buttons.

Possibly a few of the CG artists banned decensorship of their works by FAKKU in the set, but the website design team forgot to remove the purchase options from the page yet.
