Entering a search for James George Robinson (Edit - found profile with wikitree + with no dates), sort by Birthdate, select 500 results, select Exact match only.
When results are shown, check options. 100 results per page is shown, not 500. Sort is not by birthdate and there are plenty of names that are not Exact name only.
Select sort by birthdate and results are sorted, but there are other names, other than only James George, ie James William, Jacobus Roberts, Robeson, etc. Option of 'no, only exact name matches' is still selected.
Changing to 500 per page works, but there are still other names in the list. Selecting Next page gets a lot of names that are not exact names.
Edit - Using wikitree +, searching for James George LastNameAtBirth=robinson returned 4 records
