Meat prepared in a forge doesnt stack with food prepared in a pitfire, also having different decay multipliers, so, for convenience, i think it should say "charcoal grilled" or "campfire cooked".
As for for other fooods, they also dont display "brined" os "pickled".
I havent tested but i assume salted meat also doesnt display "salted"

It does, due to the different traits. There's a bug in said version with traits not getting displayed. Otherwise duplicate of #1217
