Schema aggregate ratings incorrect values

Question

does anyone know why google is reporting incorrect values in this image?

Answer 1

As you are using http://data-vocabulary.org/Review-aggregate this is the correct format:

<div itemscope itemtype="http://data-vocabulary.org/Review-aggregate">
  <span itemprop="itemreviewed">My item</span>
  <span itemprop="rating" itemscope itemtype="http://data-vocabulary.org/Rating">
    <span itemprop="average">9</span>
    out of <span itemprop="best">10</span>
  </span>
  based on <span itemprop="votes">5</span> ratings.
  <span itemprop="count">5</span> user reviews.
</div>

Using meta:

<div itemscope itemtype="http://data-vocabulary.org/Review-aggregate">
  <span itemprop="itemreviewed">My item</span>
  <span itemprop="rating" itemscope itemtype="http://data-vocabulary.org/Rating">
    <meta itemprop="average" content="9" />
    <meta itemprop="best" content="10" />
  </span>
  <meta itemprop="votes" content="5" />
  <meta itemprop="count" content="5" />
</div>

Answer 2

it should be

<meta itemprop="ratingValue" content="5">
<meta itemprop="bestRating" content="10">
<meta itemprop="worstRating" content="0">

respectively.
