We had an issue on a TYPO3 6.2.31 site. The tx_news extension did not render the og and meta description inside the head.
Below you can find a solution for this problem:
Open the following file: news/Classes/ViewHelpers/MetaTagViewHelper.php
On line 84 you can find:
$pageRenderer->addMetaTag($this->tag->render());
Renamed the line to:
// Will not render the meta tags on TYPO3 6.2.X:
//$pageRenderer->addMetaTag($this->tag->render());
// Below line is a workaround and will place the meta tags right above the </head>.
$pageRenderer->addHeaderData($this->tag->render());
