Expected Result

When adding more than 15 redirects, pagination comes into play. Since redirects can have wildcards, it is important to be able to order the redirects to get the correct behavior.

Actual Result

With more than 15 redirects, the last row on the first page has no down-arrow to move the redirect from position 15 to position 16. Similarly, on page two, the first row has now up-arrow to move the redirect from position 16 to position 15.
