My favourites, when showing "Date Added", do not actually sort by the date I added them to my favourites. Most do, a handful do not.

Not entirely sure how to consistently reproduce as it just started happening and I can't seem to change its behavior, but it's happening right now for me.

My main first avatar, which I always keep up the top by unfavouriting and refavouriting, is now bumped low.

Previously, this avatar would always be up the top of my list.

The 2 highlighted are usually near the top.

Also for some reason I can see a section called "SDK Test Avatars" - not sure I'm meant to see that section. I did not upload that one. I did upload the SDK test avatar, but I didn't call it that, and my copy is under uploaded. Not sure if related, but might as well mention.
