I have this issue I can’t understand. My front page shows up in an old version to the public (when I’m not logged in) and in a the new and correct version when I’m logged in. Specifically Section: Testimonials
I cleared WP Fastest Cache and then opened home page in Pro page builder and the contents are in sync. Please see the screencast. https://cl.ly/0t1X1W0l3m09
However, I noticed that you are using quite old version of Pro Theme 1.2.7. I suggest you to please update Pro Theme to the most recent version 2.0.4 as running old version of themes can have potential issues and plus more importantly you are missing some cool new features we have launched in Pro theme like design cloud.
