We are currently using 5.1.4. I created a page template in a space and added a label to the template. The label is "a13".
User create pages from the template and the label is present just as it should be.
After a month I change the labels using the Label edit on the pages. I remove "a13" and add "a13done".
On another page I have 2 "Page Properties Report" macros. On that lists all the "a13" labeled pages and another that list the "a13done" labeled pages.
The problem is that anytime you view the pages where "a13" was removed, "a13" reappears and you have to remove it again.
Once removed, and the page NOT refreshed, I click on the bread crumb back to the page with the "Page Properties Report" macros and the show up in the correct macro.
Again everytime you view the pages where the label from the template is removed the original label reappears.
