iOS 7 bold text problem!

Edit: Fixed. Forgot the setting is under accessibility, my bad! Who feels stupid now? Haha.

Hey guys,

I have a bit of a dilemma. I've been loving the new iOS 7 and the nice thin font that makes it look nice, however out of curiosity I thought I would switch to bold just to see what it looked like. I decided i do actually prefer the thinner font but it seems to be that once you switch to bold you can't switch back as the bold text option switch completely disappears.

I really need some help in switching it back to thin, have any of you had this problem, if so, how did you fix it?

All help will be appreciated, thanks.
