I cannot start a new campaign

This describes what I am experiencing.

Unable to start new campaign (WoL)?

I just finished replaying the original campaign in SC/SC:BW and was hoping to start a new game and play through the three campaigns in SC2, however after selecting “Wings of Liberty > More > New Campaign” I’m presented only with the initial cut-scene, and then brought back to my archives table from my previous play-through. Is there something I’m missing?
