I added some meta open graph (Twitter, Facebook) to my page, but it breaks my breadcrumb structured data in Structured Data Testing Tool.I have no idea where http://ogp.me/* coming from. Here is the source code of the page. The page itself. The page in SDTTIf I check the breadcrumb code alone in the SDTT, then it is valid.  <meta property=og:title content=Dema CORSA 9.0 green-white 540 mm />    <meta property=og:type content=website />    <meta property=og:site_name content=mihalko.eu />    <meta property=og:image content=http://mihalko.eu/image/data/dema-ktlg/B15020.jpg />    <meta property=og:url content=http://mihalko.eu/dema-corsa-90-green-white-540-mm />    <meta property=fb:admins content=1158837854 />    <meta property=og:description content=Popis -            pecifikcia bicykla DEMA CORSA 9.0                 Rm                 DEMA Road Race Carbon Monocoque, Di2              Tlmi               -               Vidlica                 DEMA Road Carbon fork / Carbon tapered steerer              Meni               SHIMANO Ultegra RD-6800 SS (11Speed)                Premka               SHIMANO Ultegra FD-6800,... />    <meta property=twitter:card content=product />    <meta property=twitter:site content=mihalko.eu />    <meta property=twitter:creator content=mihalko.eu />    <meta property=twitter:title content=Dema CORSA 9.0 green-white 540 mm />    <meta property=twitter:image content=http://mihalko.eu/image/data/dema-ktlg/B15020.jpg />    <meta property=twitter:description content=Popis -           pecifikcia bicykla DEMA CORSA 9.0                 Rm                 DEMA Road Race Carbon Monocoque, Di2              Tlmi               -               Vidlica                 DEMA Road Carbon fork / Carbon tapered steerer              Meni               SHIMANO Ultegra RD-6800 SS (11Speed)                Premka               SHIMANO Ultegra FD-6800,... />    <meta property=twitter:label1 content=Cena: />    <meta property=twitter:data1 content=2 199,99 />    <meta property=twitter:label2 content=Dostupnos: />    <meta property=twitter:data2 content=Dostupn /><div class=breadcrumb    xmlns:v=http://rdf.data-vocabulary.org/#>    <span  typeof=v:Breadcrumb>        <a href='http://mihalko.eu/index.php?route=common/home' rel=v:url property=v:title>vod</a>        <span rel='v:child' typeof=v:Breadcrumb>            <a href='http://mihalko.eu/dema-2015' rel=v:url property=v:title>DEMA - 2015</a>            <span rel='v:child' typeof=v:Breadcrumb>                <a href='http://mihalko.eu/dema-2015/cestne-1' rel=v:url property=v:title>Cestn</a>                <span rel=v:child typeof=v:Breadcrumb id=lastitem>                    <a href='http://mihalko.eu/dema-corsa-90-green-white-540-mm' rel=v:url property=v:title id=bread-lastitem-link>CORSA 9.0 green-white 540 mm</a>                </span>            </span>        </span>    </span></div>
