Part of my info is missing

All

The link is to my work website, and if you scroll down the screen to the testimonials, you will see some quotes from customers.

Problem is I have 19 quotes in total, and you can only see four of them on the site

Can anyone give me guidance as to how I can make sure all of them are showing? I looked in the dashboard, and they are all there, but not all are showing on the front end of the site

Regards
Curt
