tx_news arkicle title is not appearing on Facebook, Twitter and Xing

When I post this tx_news article link on different social media plattforms:

www.meinedomain/news-article/title-of-article/ (ex hidden: www.meinedomain/company/media-press/news-article/title-of-article/)

... instead of the News Article Title, I'll get intemedate path 'News Article' as header title of the post in Facebook, Xing and Twitter:

Facebook:
Link: yes
Picture: yes
Headline: News Articles and not Title
Teaser: yes

Xing:
Link: yes
Picture: yes
Headline: News Articles and not Title
Teaser: yes

Linkedin:
Link: yes
Picture: yes
Headline: yes
Teaser: no

Google+:
Link: yes
Picture: yes
Headline: yes
Teaser: no

Twitter:
Link: yes
Picture: yes
Headline: News Articles and not Title
Teaser: yes

How can I get the desired header on Facebook, Xing and Twitter as well? I'm also using tx_metaseo if relevant

Thats my source code:

<meta property="og:title" content="Some Title - Weekly Update (June 12-18, 2017)" />
<meta property="og:url" content="mydomain/news-articles/some-title-weekly-update-june-12-18-2017/" />
...
<title>News Articles&nbsp;&#124; Some Company</title>
...
<meta name="DCTERMS.title" content="News Articles">
...
<meta property="og:title" content="News Articles">
...

Solution

As you can see in your source code the og:title tag is given twice. Look at your typoscript if you set the og:title tag manually. Disable the typoscript og:title for your news detail page so the fluid og:title is the only one.
