The original title will show if there is no AKA title for the country/language you have selected in your profile, or if you have selected the setting for displaying original titles. Check your settings in your user profile; click your account name in the upper right corner of the site, next to the link to "Help", select Your Account, then "Update general site preferences", and check the settings in the Title display country and Title display language boxes, and make sure they are set the way you prefer.
If the original title still shows up after selecting the preferred choices then it is probably because there is no AKA title for your country.
