Lunar Revel Shop... Two of my first offered skins vanished and I got two new ones.

Okay, so when I first downloaded the patch and checked my Lunar Revel Shop, I was offered:

Marauder Ashe Buccaneer Tristana Apocalyptic Brand Scarlet Hammer Poppy Royal Guard Fiora Officer Caitlyn

Now, I just went to view it again to possibly purchase some of them and two of my rectangles were covered up again, as if I had never opened them yet. They were in the place of Buccaneer Tristana and Royal Guard Fiora. I assumed it was a bug so I clicked on them again and was offered two different skins: Dark Valkyrie Diana and Cryocore Brand.

Really weird. Has this happened to anyone else?
