Storybook bookmarks not working?

I recently purchased 3 Bookmarks from the shop for storybook, but the 3 bookmarks are still showing up as locked when I open the bookmarks inventory in game. Not sure if this is a delay between purchasing or if something has actually gone wrong. Under the recent supporters tab I can see my username ShriekingPotato and my matching skin clearly showing alongside recent purchase of 3 bookmarks. Would love to have this fixed or to know what's happening if it is just a delay. Thanks!
