Entities Support

I'm trying to use fb_social comments to replace core comments in a Drupal Commerce environment which makes use of Entities.

It seems that either I miss something essential or fb_social doesn't support Entities, because the core comments get replaced on all content types, but not on the Entities.

Tried to use the block instead but it does not appear on the entities. It's not theme related, tried it with several themes.

Can anybody help me?
