How to disable rating

Hi, I love this plugin, but have a problem. We don’t want to use star ratings, and have disabled it in the plugin (removed the checkmark at the “Enable the 5 star rating box?”).

However, the html code that is generated still spits out ratings. The problem is that these ratings are picked up by google and show on the search results. The rating value even somehow defaults to ‘1’. This is a snippet of the produced code, with star ratings disabled and no rating given:

“reviewRating”:{“@type”:”Rating”,”worstRating”:1,”bestRating”:5,”ratingValue”:1}

This looks like a bug. Can you fix it?

Thanks in advance.
