• Hosts with "Down" status (item data is not collected) will disappear from widget.
• Hosts are not shown if ordering column data is not collected. If ordering column is changed to column with collected data, then widget is showing all hosts.

This is non-intuitive and strange behavior and must be fixed:

• Show result rows if any column contains data, no matter of ordering column;
• if "Host name" is defined in the column list then hosts must be displayed, no matter if other columns contains data or not.
