The Updated filter group consists of a time interval filter:

With this filter, you can limit the displayed BI data to the nodes which have been updated (changed) on or after a specified date (inclusive), before a date, or in a time interval.

Tip
The update date and time is displayed for all BI objects in the Updated column of the Content Area.

 

You can cancel this filter by clicking None in the calendar, or by pressing Delete in the field.
