That will not fix automatic maintenance categories, such as in this case when you're trying to link to a file that cannot be found. You're missing "32px-Achievement_reputation_kirintor_offensive.png" for the icon next to "Kirin Tor (Formerly)". Once that's uploaded it should automatically go (if that's the only missing image).
