Always reset the behavior playback timelines before performing any operations on objects.
Behavior icons show a link icon if they are linked, and an additional icon if one of the behaviors in their group is selected.
To remove a behavior from the group of linked behaviors, select Unlink Behavior from its right mouse button menu.
The behavior is not linked any longer.
To unlink the entire group: reset the group in its Control window, close its control window, and then select Unlink Behavior Group from the right mouse menu over any of its linked behaviors.
