You're not missing anything. I keep on forgetting to look into this and see what is giong on and just haven't done so yet. Without asking around our office, it could be part of our indexing process that will clear this up which happens at 7am and 7pm each day PST. Has it been like that for more than one day?
For performance reasons there are some items that won't change until after the index process runs - things like auto health, deleting a workspace type, search index and maybe this one you mention.
I will try to find out and post up.
