Social Merge Tags

Social Merge Tags

I have associated my company with Zoho and Facebook/Twitter. One autoresponder I have gives me the option to place the social merge tags in the email but they do not show up when I preview.

The second and new email I am working on does not even give me the option to insert the social merge tags. It is also missing many of my custom merge tags. 

How do I get these back and working properly?

Second question. I know how to merge your facebook and twitter but what about Pinterest and Google Plus, etc. How do you sync those with the tags?
