@Malevolent Teaparty; Unless you're talking about the AI workstation, you actually need to set a colonist to be a manager, and build a managing desk. Said colonist will then start performing managing jobs, which in turn will create the designations for your lumberjacks/hunters/etc.

Oh I did that. It was some version issue I guess I reinstalled everything and it started working. Thank you for the wonderful mods, by the way.
