Hi,
The problem you have is actually that you have a third party plugin or some kind of customization which add this on the page:

It contains extra rich snippets to send the reviews data to google.
However, this plugin/customization treats a vote as a review, but without sending the author for votes.
In HikaShop's rich snippet, we only send reviews as reviews and thus this is a non issue.
So you would have to check with the developer of the code adding these rich snippets for the votes on the page to either send the author for the votes or omit the votes in there.
