Control the data facebook fetch and post on "share"
Ok, so the problem was that on the admin -> configuration -> Metatag -> open-graph.  I had the token [node:summary] on the description field. 
I do not have a field on my site called summary.
This token just fetch a lot of information from the content / view and post it.

I removed it, change it to tokens I wanted, add some text to make the output more readable, and that's it. 

After that, it took time for the site to update with the changes..
