Why is Pay with a Like interfering with Feedburner daily email to blog subscribers?

I've recently installed Pay with a Like and for some reason it is interfering with the daily email that is sent out to our blog subscribers through email. Before installation of the plugin, the email generated by Feedburner would include title and full length text of the blog each day. Now, after installation of the plugin, the email is still sent from Feedburner but there's only the excerpt is included in the email with the text from Pay with a Like that says, "To see the full content of this post/page for FREE, share this post/page by clicking one of the buttons below." Note, no post of my blog has yet to be enabled with this plugin. I want my email subscribers to be able to see the full length of the blog in their email without 'Liking' it.
