You can see it more clearly in the video here.
In the upper left of the Details view is the word [color=#ff0000;]Filtered[/color]. I right-clicked on the first name - Delilah Woods - in the Details view (you can rightclick anywhere in the Details view). This opened up the right-click menu where the Filter options are listed. I un-checked the filter that was selected. That got rid of the [color=#ff0000;]Filtered[/color].
If you aren't familiar with that rightclick menu, you may want to explore some of the options - like adding different columns to the Details view. Many screens in TMG have rightclick menus, so it is something to look for.
Were you able to restore your toolbars and icons?
