First of all, the trait "Pneumonic" trait should be "Pneumonic Plague" (Devs please read). Then it should be more powerful than the "Bubonic Plague" trait, since the Pneumonic Plague attacks lungs.

Pneumonic inidicates someone who has Pneumonia, a completely different disease from Bubonic Plague..
Well, not exactly.
Pneumonia is not itself really a disease, but inflammation of the lungs caused by some other disease like bubonic plague (bacterial), SARS (a virus), malaria (a parasite), etc. Many diseases can cause pneumonia.
But the OP is clearly a little confused.
