Site name on linkedin not showing

I changed the site name in my settings. However, when I want to share the link to my home page on linkedin, the site name doest show. We can only read “Site Name”
Could you advise how to fix this ?
I’ve shared two pictures: on the left my settings, on the right the preview on linkedin

Thank you

it looks even worse when I share it by message on linkeding
It strange cause I also wrote a description

Is it updated on the live version? Also, there may be some caching going on on LinkedIn’s side.
