Items/Elements on the Navigation Bar Transition

[federicodiaz1]

Hi! When I go to a previous screen (slowly swiping to the right) the elements on the next screen navBar show as soon as I start swiping, when in iOS 13/12 they show progressively from left to right.
Any idea what could it be? I was thinking about bar.items in the UIViewController+KMNavigationBarTransition.m file

iOS 14

iOS 12
