Hello, I have minecraft 1.12.2 with MCA 1.12.2-6.1.0 and whenever I beging a new world and find a village I interact with all the villagers and none of them have a trade option all of them have the same menu (interact, work, ride a horse, etc). I have found the cartographer to trade the wood/forest mantion map but he doesn't have the trade menu nor any of the villagers. How do I get that trading option? becouse in the entire world not any single villager has that option.

I'm sorry if this is not an issue and I have to do something to unlock that option, I'm a new minecraft player so I'm not familiar with this. Please I would like to get some help here.
