Viewing on live site

Hi, I am testing your plugin. I have gone through the options, but still can’t get it to display the ‘arrow up or down’ in the settings or layout editor. Once selected and saved the live site still doesn’t show it. It is sliding but NO arrov on the bottom when I choose the correct layout also. I also tried layout editor and chose what I wanted to display. I am also using the Featured Image that displays fine. Also when it displays the Testimonials it is ONLY 3 lines it shows, some testimonials are much longer. I tried to display the “more” also but still not showing. Not sure what I am doing wrong. How do I change the colour of the testimonial also ? Thx Kristin
