In order to get the renewal points you will have had to be part of the gold membership and not a silver account when you renewed.
If you were gold when you renewed the membership then the points will be added to your pending list on the actual date of renewal. For example: Your current membership does not end until April 24. You decide to add more gold to stack it. On April 24,
the points for renewal will show as pending on your list.
For further clarification or if you have more questions you should post in the Rewards Forums.
