Testimonials not displaying correctly in carousel

Hi, I am trying to set up testimonials and find that anywhere I try to add them, there is one slide in the carousel where two testimonials are stacked, and at the end, one blank testimonial. This happens every time, on any page. For example, from the sample data, this page: http://cities.enhabit.org/testimonials/

I’d like to show one testimonial per slide and remove the blank slide. Thanks.
