Not the items on the list, but the lists themselves.

On the My List page, custom lists used to appear after the defaults lists in alphabetical order, but that is no longer the case.

Also, on an individual series page (E.G.) the "add to" or "move to" "Select..." box has the lists all jumbled up and not in alphabetical order.

This becomes a massive frustration when one has many lists.

Update: Lists are no longer in Alphabetical order on the "My lists" page either.

This is now resolved, but it may take about an hour for the cache server to expire. I think you can trigger a faster update by "editing" your custom lists but making no changes (or a minor change and changing it back). Otherwise it should be good in an hour.
