If you press 6-9 or 0, do you get a message? (No pawns selected or something like that?)
If not, then maybe you didn't have Miscellaneous active, when you started the colony?
That function and the anomaly incident use a MapComponent. This is a part that is added to a colony, when it's created.
It is not easy to add it later on. (Manual changing of the savegame is required to do this).
