Phantom Labels

Changes made to labels are not registering int he system. I made several label changes, and after I made the changes, and click to view all pages with the new label, it states that there are no pages at this time, although the label is clearly shown on the page. I also deleted the labels from several pages, but these still show up when I click the first label in the tag cloud.

I appears that something in the system has not registered that the labels were changed/deleted.

To replicate:
1. Create page and add any label to it.
2. Click on the label – no pages will show up for this label.
3. Delete any label from already existing page.
4. Then click on the label from another page. The page from which you deleted the label will still appear.
