I can not turn the "english title" on. I mean, althought in my profile I set the Language Preference: to Official Title (English). Some anime like "The Melody of Oblivion" appears as "Boukyaku no Senritsu". In fact, someone readded the anime, just today, as "Melody of Oblivion" because he/she didn't find it by his english title.
The naming feature has become too complicated it seems.
It appears like that on the anime's page and thus the mylist-link is wrong, indeed. Is that what you meant or did you really see that anime in your mylist as "Boukyaku no Senritsu" while having the Preferences set to "English (Official)"?
