Bug report - PHP Notice: Notice: Undefined property

I'm debugging my site and your plugin PopUp Pro (v. ) is producing following notices: it would be great if you'll fix them in next release, it's annoying even if you can ignore it.

Notice: Undefined property: stdClass::$delete_posts in /home/www/xyz.cz/www/xyz.cz/wp-admin/includes/class-wp-posts-list-table.php on line 251

Notice: Undefined index: normal in /home/www/xyz.cz/www/xyz.cz/wp-content/plugins/popover/inc/class-popup-admin.php on line 946

Notice: Undefined index: advanced in /home/www/xyz.cz/www/xyz.cz/wp-content/plugins/popover/inc/class-popup-admin.php on line 947
