Why my Microdata has errors on Google Structured Data Testing Tool?

Question

I cannot figure out what is wrong here? I get error missing location,name,startDate while clearly it is there! I am using schema.org microdata.

The weird thing is that I get 10 valid postalAddress tags like they are not under the main itemscope.

<div itemscope itemtype="http://schema.org/SportsEvent">
          <td>
            <a itemprop="url" href="/match/10254">
              <meta itemprop="name" content="SKA Rostov na Donu vs Kuban Krasnodar">
              <div itemprop="location" itemscope itemtype="http://schema.org/PostalAddress">
                <meta itemprop="addressCountry" content="Russia">
              </div>
              <span itemprop="homeTeam">SKA Rostov na Donu</span> vs <span itemprop="awayTeam"> Kuban Krasnodar</span>
            </a>
          </td>
          <td> <small>
            <meta itemprop="startDate" content="2015-09-28T17:00:00.000Z">
            <span>Sep 28 17:00</span>
          </small>
        </td>
      </div>

Answer 1

the testing tool is clear with error descriptions: you haven't applied required properties. If you add location as Type PostalAddress, so you MUST add address and (stadion)name. Location by its own should have its own name too, not only as postalAddress. And avoid usage of relative urls like urls - they could be not correctly recognized.

Update: following markup is validated errorfree:

<div itemscope itemtype="http://schema.org/SportsEvent">
          <td>
            <a itemprop="url" href="http://www.website.com/match/10254">
              <meta itemprop="name" content="SKA Rostov na Donu vs Kuban Krasnodar">
              <div itemprop="location" itemscope itemtype="http://schema.org/Place">
               <meta itemprop="name" content="Stadion Bezimjannyj">
                <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
                 <meta itemprop="addressCountry" content="Russia">
                 <meta itemprop="streetAddress" content="Uliza Lenina 666">            
               </div>
              </div>
              <span itemprop="homeTeam">SKA Rostov na Donu</span> vs <span itemprop="awayTeam"> Kuban Krasnodar</span>
            </a>
          </td>
          <td> <small>
            <meta itemprop="startDate" content="2015-09-28T17:00:00.000Z">
            <span>Sep 28 17:00</span>
          </small>
        </td>
      </div>
