MarketPress doubling shipping cost and Products page showing extra text at the beginning

Just got MarketPress yesterday and love it! However, have 2 little issues:

(1) My Products page is showing some text prior to the list of books and a photo, that are not even part of my "Products" at all - please see:

(2) The shipping fee of $3 is being doubled to $6!!

I would greatly appreciate your direction on how to resolve this ASAP!! Thank you so very much for your assistance!
