[Hummingbird Pro] Blocking Search Console

Hi Guys,
I have installed Humming Bird and set up the cache for a new site we have been working on. I am now getting mobile readability issues from Google Search Console (see screen shot attached). Any ideas what might be causing this?

I have also noticed GTMetrix loads the site in 2.x seconds but Google Lighthouse rates it at about 18 seconds.

Any ideas?
