The Plugin Event-Post prints the [:lang] Tags in Widget

I have a Problem. The Plugin Event-Post Print-out the [:lang] Tags in the Widget. I think this Code here and spezial the line $event->post_title, ist responsible for the problem. Does anyone has a idea how to fix this?

$list.=str_replace(
                        apply_filters('eventpost_item_scheme_entities', array(
                    '%child%',
                    '%class%',
                    '%color%',
                    '%event_link%',
                    '%event_thumbnail%',
                    '%event_title%',
                    '%event_date%',
                    '%event_cat%',
                    '%event_location%',
                    '%event_excerpt%'
                        )), apply_filters('eventpost_item_scheme_values', array(
                    $child,
                    $class_item,
                    $event->color,
                    $event->permalink,
                    $thumbnail == true ? '<span class="event_thumbnail_wrap">' . get_the_post_thumbnail($event->root_ID, !empty($thumbnail_size) ? $thumbnail_size : 'thumbnail', array('class' => 'attachment-thumbnail wp-post-image event_thumbnail')) . '</span>' : '',
                    $event->post_title,
                    $this->get_singledate($event, '', $context),
                    $this->get_singlecat($event, '', $context),
                    $this->get_singleloc($event, '', $context),
                    $excerpt == true && $event->post_excerpt!='' ? '<span class="event_exerpt">'.$event->post_excerpt.'</span>' : '',
                    ), $event), $item_schema
                );
