I receive the following when integrating this module into a create-react-app. It looks like that the react-transition-group has props that are no longer valid. Can anyone confirm this?

index.js:2178 Warning: React does not recognize the `transitionName` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `transitionname` instead. If you accidentally passed it from a parent component, remove it from the DOM element.
