Although I entered codes AND used tham too, I am still warned that my points are to be expired.

On 9/3 I entered bunch of new codes and filled the weekly allowance. After that I made two purchases using my points. Today (9/4) I received a mail warning me that my points are about to expire. I checked the web site if the error was corrected, but the warning was still there. Is this normal procedure and the warning will dissappear only when I delete it? I do not want my points to expire by a technical error. Thank you for your help.
