"Skilled : Super-Duperhard Digging" doesn't work

Not a bug, just counterintuitive. Having superduper hard digging doesn't automatically grant hard digging and super hard digging. So the dupe can dig diamond but not granite until you give him hard digging.

Granite requires level 1 hard digging, not level 3 hard digging. I'm not sure if this is intended behavior or not, but having level 3 doesn't automatically give you level 1.

This is how it works at the moment, even if unintuitive.

My dupe has been given the first hard digging skill. "Skilled: superhard digging" should unlock superhard digging abilities without spending a skill point, yes? It does not. Please explain further or ask me for my save file. The attribute in question doesn't appear to do anything. The dupe is unable to mine Abyssalite.
