The “register code” is in wpresidence/libs/ajax_functions.php , function wpestate_ajax_register_user

the user level is set via this code

update_user_meta( $user_id, ‘user_estate_role’, $new_user_type) ;

​$new_user_type is set via $new_user_type = intval($_POST[‘new_user_type’]);

Because of the intval function , if there is nothing in $_POST[‘new_user_type’] the value saved will be 0

You can set the value by checking $_POST[‘new_user_type’] and setting 1,2 etc according to the level you want .User Role (1, 2 , 3 or 4): 1 = simple user, 2 = agent, 3 = agency, 4 = developer
