cfdb7_before_save_data Filter

Hello,
there is a filter cfdb7_before_save_data and if I use this hook in my code add_filter('cfdb7_before_save_data' ... it executes twice per one submit.

Solution: remove the unneeded do_action( 'cfdb7_before_save_data', $form_data ); from plugin code contact-form-cfdb-7.php line 132.

Tnx
