PDF pages out of order

Jen, greetings from viovio. Please email your product ID to support@prestophoto.com so we can look into this further.

Thanks,
PrestoPhoto support

Hello again, I'm having ongoing problems trying to get an iPhoto book formatted properly in PrestoPhoto. Initially it wasn't recognizing my first page which shifted everything out of order. So I added a page and redownloaded. This solved my initial problem but then I looked through the entire album and at the very end a couple pages have been flip flopped. I reviewed my pdf and it's in the correct order (ie. different from viovio) so I don't know why or how this happened. Any suggestions? Thanks!
