Xcode Storyboard iOS 7 navigation issue

I'm creating an app with some nested navigation.


I've got a Navigation Controller with a Login page in it. Logging in through a button directs to a Tab Bar Controller using a "Show Detail" segue. The first tab contains a View Controller embedded in a Navigation Controller.


This should be more clear:

Navigation Controller -> Login page (View Controller) -> Tab Bar Controller -> Navigation Controller -> Table page (View Controller) -> Table detail page (View Controller)


Everything works as expected in both iOS 9 and iOS 8.


I get problems with iOS 7 on iPhone 4S. Whenever I log in and get to the first tab, instead of the Navigation Bar with the title, I have a Back Button in the bar, that allows to return to the login page. Even if I have specified a ""Show Detail" segue.


I don't know if I'm doing something wrong as it works in iOS8/9, or if it's a bug.


Thanks.
