Calendar Question

I am trying to order a calendar. I've finished it with the 4:3 Landscape book, and when I go to check out, it gives me the option for the Wire-O binding. The only problem is eventhough I designed it with a cover and then 24 pages (2 for each month), they have inserted a "inside front cover" when I view it through the preview. This obviously throws off the whole calendar. I'm wondering if it was just a preview if it were to be a book, and that I can go ahead and order the calendar and that it would turn out OK. I'm ordering 5 calendars, though, so I definitely want to know the answer before I order. :) I'm ready to check out and pay as soon as I get the answer. Thanks so much.
