Can’t clear plugin flag

I had five plugins that needed to be upgraded after I installed WordPress 2.6. Three of them were active, and two of them were plugins I really didn’t need anymore. So I upgraded the three for my active plugins, and I took a minute to delete four or five plugins in my “Inactive” section which I didn’t need, including the two asking the be updated.

The plugin flag in the top right corner that shows that I have plugins to update decremented for three active plugins that were updated, but it didn’t decrement for the two plugins that are now deleted.

How do I clear that flag?

Thanks!
