Adding schema to schema in header

Hi there!

When I check “Enable Google Rich Snippets?” it appears as though this adds schema to the page outside of where I have previously added schema.

You can see the issue if you search “schema” here:

view-source:https://simmereddown.com/recipes/massaman-curry/

Google’s Structured Data Testing Tool registers this as two different schema markups: https://i.imgur.com/WrjCeWE.png

Is there any way to add the “review” schema to the schema I have already added to my header.php?

The page I need help with: [log in to see the link]
