Document: Count of nodes not updated when node update

When the option "Show count of nodes in categories" is selected, the numbers in the directory are accurate. When I changed one of the node's (my first) terms, the numbers weren't updated next time I clicked "directory." refreshed the page -- nothing. I don't know how the directory processes this, but it doesn't seem to process a change in the node's selected terms.

Note: I have multiple select set and had multiple terms selected. When I went t back to the directory settings and unset/reset the option, the numbers were accurate again.
