Pinch and Rotate gestures called all the time no matter what on Mobile?

I am in the process of creating a mobile app using Unreal. I discovered that there are built in gestures for things like pinch and rotate. All I have done is add the event to my graph and added a print string to both. I have deployed it to a phone. Whenever I go to test this, both events are called at the same time no matter what my finger positions are. Essentially, the events are just being called whenever two fingers are touching the screen. Is there no other logic behind these events other than just checking if two fingers are touching the screen?
