Card design bug – Dunkin' Review

This issue is consistent. If I go to my card and press design to pick a new one or swap it out for a new one, it shows up but when I exit out of the app and go back in, it reverts to the old card design. Please respond to my message if you can and let me know if this is something that you can fix. Thanks.
