Muse Blog custom fields (Solved)

*EDIT: SOLVED I figured it out. Applied the graphic style to the whole post container by accident instead of the custom field I'd added.

I've been trying to figure out how to add two custom fields back in after having deleted them early on thinking I didn't need them (I want to add one to show the price of a print, and one to paste Paypal button html into) and in trying to do this, suddenly my blog which was working fine, now has the sample blog post stuck on it. How do I fix this?! I tried deleting the two custom fields I had attempted to add and place Graphic Styles onto but deleting them didn't change the blog back to how it was. Help!!!
