CCAPS Not being added to existing CCAPS in member profile

Hi,

I have a customer setup using ccaps to protect areas of pages within their site.
Users are initially signed up when they purchase their 1st set of ccaps (not a subscription, the sort that just last forever) (this works fine).
However, if that same user goes on to purchase a 2nd set of ccaps (for access to other parts of the site), they are told to log in, the purchase form inherits their profile details, as expected, the purchase goes through paypal fine, and returns to the site displaying the correct messages, BUT the 2nd set of ccaps are not added to the user profile.

Could anyone point me in the right direction of what the issue could be please?

Thanks in advance.

Jim

PS: Membership level is being added correctly on initial purchase as well.

We are having a similar issue. Any response to this question?
