The font looks BOLD in page 1 but looks correct in page 2/3. The font is exactly the same (from what I can tell). It also seems to be a page thing, because I can drag the font to page 2/3 and it looks correct. Drag it back to page 1 and it looks bold.
Is there an image, or an element with an applied effect on the page that is displaying a bold font? If so, try putting the text on its own separate layer.
