Error on new install

I was going to move from legal to Entity Legal however after installing the module, when I go to create a new legal document I get the following error:

PDOException: SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: 'terms_of_service' for column 'entity_id' at row 1: INSERT INTO {entity_modified} (entity_type, entity_id, modified) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2); Array ( [:db_insert_placeholder_0] => entity_legal_document [:db_insert_placeholder_1] => terms_of_service [:db_insert_placeholder_2] => 1443140169 ) in entity_modified_entity_update() (line 50 of /home/site/public_html/sites/all/modules/contrib/entity_modified/entity_modified.module).
