[Hummingbird Pro] Identify cached pages

I have “Identify cached pages” turned on and I’ve entered the url for a page that should not be cached : https://rapidregisteredagent.com/leave-a-testimonial/. But when I look at the source code for that page and another page that should be cached (like https://rapidregisteredagent.com/why-us/), I cannot see a comment indicating the later is cached.
