Though we can alter text in product previews after clicking "Done" because "Personalize" is provided, we don't have this ability on business cards. We can't check whether everything has been done correctly unless we post the card for sale.
Is this a bug or has it been this way for a while?
ColsCreations, thanks for the link. Sadly, it proved things have gone further awry. The create-your-own page suggested by Scott is where I was trying to design business cards. I guess for the time being, the only way is to hit the Sell button to check out how well things are working, edit to correct what's wrong, and then republish.
