The group names assigned to the bone come from the grouping of the .obj file. What we are both trying to tell you is that you have to group the figure BEFORE you enter the setup room. If you chose the Auto grouping feature, the groups and the bones will be assigned as you are seeing them now.

There are several different ways of going about what you are trying to do. If you are going in with an original figure that you created, you have to group it first. Period. 

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
