iphone installed app icon is same as app store which is wrong

I am proceeding with my development of version 2 of an app and have an icon on the app store that looks like a 'default' in that it is a set of circles with lines through it. This icon appears as the icon for the installed app on my iphone. The xcode images.xcassets appicon has the correct icon. Do I have to remove my app store entry in order to correct the icon there and if I do can I reuse the name I have when I recreate the entry?
