Parallax section header is not sticking to top while scrolling

[AtulSingh9490]

The section headers are not sticking while scrolling even if the disableStickyHeaders = false and parallaxHeaderAlwaysOnTop = true.

Also, if I do,
flowLayout.sectionHeadersPinToVisibleBounds = true

It crashes on scrolling and gives error,

Assertion failure in -[UICollectionViewData validateLayoutInRect:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3512.60.7/UICollectionViewData.m:408
