"review" field is missing

Currently it looks like you are only creating the review field for Submitted or Manual reviews.

Are you sure you have those types of reviews on the page?

3 themes are active, and this status is active in all three of them. Screenshots are below.

I think you misunderstand. The Manual & Submitted will only use reviews that were manually input on the Review List or Submitted on the site through a form. Reviews that are download like Google will not show in the schema. You would need to change it to "All" in order to show those. However, I would not advise that as Google does not like you to use reviews from other sites in the schema.

What's your suggestion Josh so I don't get this error?

I want it to appear as starred page on all pages in google searches.. Can you help me?

Answer please Josh :(

Just turn off the individual markup.
