Why are the reviews on my recipes not showing up on google?

I'm not sure if this is the right forum, but the reviews on the recipes on my website are not showing up on google search. I have attached a picture of what one of my recipes comes up like on google search. Mine is the first recipe pictured that says "no reviews." But, it does have a review (I use a powr plugin). Does anyone know how to fix this? 

I've seen this issue before actually, the problem is with the plugin you're using. The plugin information it displays doesn't follow the proper format for Google SEO/Rating codes.

The best option is to either create a markup within each post that follows the Google format, or use a new ratings plugin that logs this information for you. I read this article a long time ago, hopefully this steers you in the right direction.
