Site Admin --> Categorization --> tags
Add a tag, eg tag1
Go to DM, add more than 20 entries(say 23 entries) with the tag, tag1
Deploy tag navigation and Document Media to a page
Click tag1 in tag navigation

Expected: At bottom of Document Media, you should see "Showing 1 to 20 of 23 entries."
Real: At bottom of Document Media, you would see "Showing 1 to 20 of 21 entries."

And if you turn to next page, you would again see the expected Showing 21 to 23 of 23 entries.
