Resolved og:image property missing in the template

Hi there,

I have updated my website from newsedge template to the newsberg template. I've enabled the open graph feature from template options and provided my facebook app id. Now I'm facing a big problem when sharing an article on facebook:

1- When sharing an article from social icon, I got another article title (see the first screenshot).
Check this url please: https://wegzumislam.com/islam/missverstaendnisse/ueber-islam/1413-islam-und-idealismus

2- After sharing it on facebook, I got no image or I got alot of images with the wrong article title (see issue3.jpg). There is a mess in sharing.
I have checked it also from facebook sharing debugger, and I got an error in open graph (og:image) property is missing (see issue2.jpg)

Solutions I've tried to do:
- I tried to solve this issue with phoca open graph but no way, I got the same mess.
- I tried with tagz open graph, but I can't still using it, because it doesn't find the image in the article. I think the main issue is with image (og:image).

I hope you help me to solve this issue as quick as possible.

Regards!
