Resolved Tab order on view controller

I'm using storyboards and i have a view controller laid out with some UITextfields, it's an input screen. Somehow the tab order changed between two of the textfields. Is there any way to change it back other than delete everything off the view controller and then rebuild it? The focus disappears between two textfields and I have no idea where it goes. It's as though there is a hidden field between them.
Thank you

 

I figured it out myself, thanks.
