Hi, I bought Sidewalk crowd single file.  It didn't work as the youtube video showed it would, but I'm okay with that.  the problem is that there are these signs at the bottom of each of the characters, they say control dummy on them.  I can't figure out how to remove them.  There is nothing to click on, but If I move a character, the sign will separate from the character, but not disappear.  Will somebody please help me to figure this out?
