Weird Things Happening???

Today I went to access my First Niagara App on my iPhone after getting to the password screen it asked me to allow the Dicks Sporting Goods app to be accessed by the First Niagara App. I thought this was extremely strange but my curiosity got to me so I excepted it by pressing yes to allow. It immediately began to access the Dicks sporting good app? I closed out both apps and relaunched the First Niagara App which went from the password screen to the Dicks Sporting good app. So I erased both apps and power cycled my iPhone on & off. I preceded to add the apps back onto iPhone. First the Bank app which seemed to work just fine the I added the Dicks Sporting Good app back and once again every time I engaged the First Niagara App when it got to the password screen immediately went to the dicks sporting good app? Is this some sort of virus or hack I dont understand it makes no sense????
