In my case I just made a simple mistake when using keyExtractor
I changed
keyExtractor={(item, index) => index.toString()} To
keyExtractor={(item, index) => item.key} I was seeing some strange effect after filtering my list where props of filtered out components were being rendered in place of new component's props, my hunch is that because I was using the index of the array rather than a unique key, I was just passing the old props to the new component even though the base component was in fact changing.
