How to I get rigging with the bone tool to work?

I imported a character from illustrator into animate. I then broke it apart and distributed it to layers. When I try to use the bone tool it doesn't work. I start off with one plot and drag to the next, and then, then bone tool moves the points to the edge of a bounding box, not where I set the transformation points. Also, piece of my character just flies away out of position. Each part of my character is a symbol. However, my full character is a not a symbol. I don't know if it's supposed to be one. When I tried to make it into one, the mouth that I made stopped moving. (Some audio is attarched)

I attached 2 photos. The first photo shows the transformation point where I want to start at. The second photo shows what happens when I try to make a line with the bone tool, from the first point, then up the belly to the 2nd point. What happens, is the line moves somewhere else, and connects the line to the end of a bounding box.
