The page approval macro will show that a page is approved when the approvals have been unregistered.
The steps to replicate:
A page has 5 pending approvals with 2 quorum. This means only 2 approvals are required in order to make the page approved.
2 users approved the page. This will make the page to be approved with the date
The 2 users who approved unregistered themselves. This will remove the date of the approval
The page remains approved and the 3 other users are on the list (see image)
