Trackpad Rotating Issues

I normally use the trackpad two finger swipe to rotate about however, recently this has turned into what seems to be the zoom feature rather than rotation. I’m not sure how this happened but without that rotation, rotating around becomes very inconvenient. I was wondering if anyone knew what could cause this and how to fix it. Please let me know if I did not include enough information in order to solve the problem.

Thank you

There are some input settings in the user preferences screen. I suspect you can change it from there.
