Problema na minha conta

Hello, I come to ask if you can help me with my account. I'm realizing that my achievements don't want to be completed in my world. I haven't activated anything, just a mod to look nice, but mods don't do the same thing as activating commands or creative. When this world appears, you can't complete the achievement, it's normal, but I still can't complete my achievements. I went to the underworld to get the meat from the other pig and nothing, which was the easiest achievement, there is one to disenchant an item and gain XP I did this and nothing can you help me
