Hey there,

I am really sorry for the delay of this reply as it is a public holiday for us here.

I suspect it conflicts with the "4SEO structured data", because the Easyblog structure schema data (aggregate rating) is showing on the blog entry page, you can check my attached screenshot below and you can compare the page source data.

You can temporarily turn off this 4SEO structure data and try checking from https://search.google.com/test/rich-results/result again and see how it goes.
