weird sql statement conditions

SQL (0.000364): SELECT i.itemid,i.hostid FROM items i WHERE i.type<>9 AND i.flags IN (0,4) AND i.itemid='31871' AND i.flags='0'
items.php:194 ? CAPIObject->get() ? CAPIObject->__call() ? czbxrpc::call() ? czbxrpc::callAPI() ? call_user_func() ? CItem->get() ? DBselect() in /home/main/usr/local/apache2/htdocs/trunk/api/classes/CItem.php:374

note the presence of both :

AND i.flags IN (0,4) AND i.itemid='31871' AND i.flags='0'

this is generated when clicking on an item in the configuration
