unrecognized links For SEO

Hi everybody,
I have a problem with links on a website and search engine on the internet. is that I can not share them on social networks and I can not be indexed on search engines. the crawlers do not know them.
I am based on a plugin called “Real estate” which I have made several changes to suit my needs.

if you have an idea about the subject or course how it will work.

The website: https://www.mbi-maroc.com
One of link that I can’t indexing or sharing in SEO :

thank you
