iTunes Connect asking screen shots for project

I've developed an app for iPhone (Portrait orientation) and with iOS 8.0. I checked that every single one of the Views are set for size of 4 inches. (I want to target iPhones 5, 5C and 5S).

Probably this is a very noob question, but I'm trying to submit an app into the itunes connect, but when I want to submit, the system replies that I need submit screen shots for 5.5 inches retina, 3.5 inches and 4.7 inches.

How do I correct this issue?, because even iPod is allowed to use my app in this moment.

Thanks guys!
