As a system super administor, I set a screen for my customer, and created a zabbix user with limited permissions (user type: zabbix user) for him, almost every thing on frontend is ok, but on screen view, there always have many errors on the bottom of the page, that are:
Undefined offset: 4 [api/classes/class.cscreen.php:361]
Invalid argument supplied for foreach() [api/classes/class.cscreen.php:361]
Undefined index: 10 [api/classes/class.cscreen.php:361]

If I change this user's type to zabbix super admin, no error found, but I don't want him to be a super admin in my system.
