Pivot Table: Not all source records have been copied. ???

when I try to create a pivot table using this small worksheet in the below link, I always get a message 'not all source records have been copied' yet it displays all source records? I have spent many hours searching for a solution with no success. Why would Excel give this error on such a simple task? it does not matter how many rows this data has 1-10000 same error, if I go to Insert -> Pivot table, select any fields in the pivot table. It counts correctly, it even displays the result correctly, but always give me the message 'not all source records have been copied' I really do not get it and any help would be amazing!
