I get the following error when I archive my application in xcode and try to send to the application store:

From what I read on other forums to solve this problem, I need to create a new startup image with a size of 320x568 and add it to my startup image file. My question is, how do I create a new placeholder in my startup image file if each placeholder is full?

As you can see, I'm not sure how to create a new placeholder in my startup image folder to add a new 320x568 image. Can someone please advise, thanks!
