It reproduced on 2.0 and 2.2 only.
Not reproducible on 2.4 or trunk.
Not sure you will want to fix it for 2.2 only, but 2.2 is LTS, so as you wish ...

Profiles table was cleaned out before experiments.

Two widgets: Status of zabbix, System status actually use 120 seconds as default refresh period though "60" is bold-ed in a drop-down menu for these widgets.

If manually select already bold-ed "60" - it starts to be used by the widgets.
In this case corresponding values are inserted to the "profiles" table.

It may mislead zabbix users.
