Reset your text palette. You have all sorts of custom formatting like negative kerning and baseline shift. also, obviously, type the text at a point where it's visible and the animation preset has done its magic.
It looks like you have applied the Fade Up animation preset. If you did move the current time indicator down the timeline a bit. If that doesn't help select the text layer and press the U key twice to reveal all modified properties. Try resetting anything that is not at the default settings.
