Compatibility issue with Enfold theme

Hi

We use the plugin on a page that is based on the Enfold theme and has two contact forms. One is located in the content section of a separate contact page while the other one is located in the footer of each website (as footer widget). Although we use the same shortcode, the form in the footer is not working. This means the form content is not sent to the registered e-mail address. When we disable Email Address Encoder everything works fine.

Any ideas why the form in the footer is not working correctly?

Many thanks!
