Remove HTML displayed on front end home page

How do I remove wrapped paragraph HTML displayed on published home page? Shown as:

<!– wp:paragraph –><p>

I’m very new to this, but I’ve searched the interwebs for days trying to find a solution. This site isn’t indexed yet as I’m in the process of building and many things aren’t final. I am using Chrome.

I am using the Total theme – content is added via Gutenberg page in a paragraph block. HTML is not shown in back-end visual editor, but is when I view published page.

I’m using the most recent update of WordPress 4.9.8 and a few (very recently activated) plugins:
Yoast
Pretty Links
Sucuri
Smush
(In addition to Monster Optin/Insights that was defaulted in)

Any help or resources will be extremely helpful!
