The URL Fragments are invalid as they use invalid characters and spacing. When saving a Commerce Category with these invalid characters, users will get the error message. To resolve this, the URL Fragment must follow the following rules;
- 1. Alphanumeric characters (A-Z, a-z)
- 2. Numbers (0-9)
- 3. Dashes (-) or Underscores (_)
After all these are within the outlined rules, users should now be able to successfully save their Commerce Categories without encountering the Unexpected Error message
