UIButton affecting UICollectionViewCell Appearance - ios

Question

Ok, I have a ViewController that contains a UICollectionView and a UIButton. The Button is Not inside the collection view. When a user taps on an item in the UICollectionView I have some code that changes the background color of a UIView in the cell to show that it is selected. I have similar code for the UIButton which changes its background color when a user taps it, so it is acting like a styled checkbox.
The issue I am seeing is when I tap an item in the collection view, it highlights as it should. But then if I tap on the button, the button highlights normally but the collection view changes which item is highlighted. Even though the button that was tapped is not inside the collection view and has no ties to the collection view.
See following images:
first image: I have tapped on an item in the collection view, see the item is highlighted as normal.
second image: Notice, here, when I tap the Im not sure button, the collectionview changes and the highlight goes to a different cell. But no code in the DidSelectCellForItemAt is running

The issue pointed out by caninster_exister is that I was reloading the collection view
