Normally you can turn the State Label off for FSM's individually in the Inspector, expand the Play Maker FSM Script on a gameObject and uncheck Show State Label.
Templates seem to revert to the Reset values for the script or something so the labels are inherently stuck On for templates it seems, since it disables the Inspector controls. I dont think you can disable them individually for Templates (as far as I can tell) and it looks like a bug more than a missing feature.
