Thank you for your recent contributions of adding Pancakeria HD information to the customers. They have improved the site greatly!
When you add the Pancakeria HD items the customer is unlocked with, somehow, a category is renamed. When you edited Mayor Mallow the first time, the category was changed from M Characters to M Charac. The second time you edited Mayor Mallow, M Charac was changed to M.
Other users have encountered this problem too, so it's not your fault.
Question: Did you even know this was happening? :)
