Items disappeared from Shop Watchlist

I had around 20 microtransactions on my watchlist earlier today. Now there are only 5.

Edit: I notice that if I go to the missing mtx's itself, they still give me the option to remove them from my watchlist, but they do not display in the watchlist.

Edit 2: I tried adding another mtx to my watchlist. It caused another mtx that had disappeared from my watchlist to re-appear. The mtx I had just added did not show up on the watchlist. When I removed it from my watchlist (using the button on the Specials page), the old mtx that had re-appeared disappeared again.

Edit 3: Not sure if this is related, but many of the microtransactions do not display the video of the effect when you click on them now. They just display a static image.

Yes, thank you
