A lot of the time they don;t add immediately to the total, but pop up an hour or two later. After you enter it the 1st time it will continue to register "Valid code" but will only add points once. Unless you have very good memory or write down the totals, they're even to miss.
If your point history shows them it seems to thing they're there. I might suggest )if you haven't already) write your to total down before adding a new code and see if the total changes eventually
