in the IDEA profile, your CPR does not have an expiration date, and you can only hide it from view or change the provider by editing it in your profile.
I saw that you are ACE certified, and in your ACE profile you can enter this information, particularly, since you will need proof of CPR to renew your certifications.
If you go to your Profile, under My Education, there may be a place for you to update your actual card dates. Although the dates may not show on your profile, the dates you add are saved under My Education. (at least it shows under my own).
Hope this helps you to update it.
