homophones

Kind of a random question. Now I know this isn't an anime group and I don't know if this is the place to ask. I'm watching Sailor Moon in Japanese with English subtitles. When Usagi introduces herself at the beginning of each episode she says she is じゅうに which is 12. However the subtitles say she's 14 and EVERYTHING I'm seeing online says she's 14. Is there something I'm missing? I've already heard/read some very obvious translation errors but this one is messing with me.

Is this the introduction to which you're referring?
