the rating system cause massive Structured Data Errors

coupon theme.

I just checked webmaster tool , there are massive errors with rating button code (schema.org/AggregateRating)

the rating system
[code title=””] <div class=”wlt_itemscope_ratingbox” itemprop=”aggregateRating” itemscope=”” itemtype=”https://schema.org/AggregateRating”&gt;
<meta itemprop=”ratingCount” content=”0″>
<meta itemprop=”ratingValue” content=”5″> [/code]

I checked google docs, under schema.org products, name field is required. but in our system, it is missing. is there anyway I can turn this schema.org off?

is it bug?
