Hello,
Thanks for getting in touch with us.
Yes, we have removed certain social networks from the social meta tab in titles & meta settings.
The same thing is mentioned in our changelog:
Removed: Multiple Social meta options, as they are not required anymore for the Knowledge Graph by Google & Bing. You should only see the needed options in the Global Social Meta settings page

We are in the process of updating the SEO Analysis tool to don’t recommend those settings, but for now, you shouldn’t worry about them since they are no longer supported.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
