When my world was in 1.15 I completed the "Monsters Hunted" and the "Adventuring Time" advancements. Then I updated it, it rememberd the old biomes and mobs so only the new ones remained, the problem is that when I did kill/explre a new mob/biome it doesn't count in the advancements.
Btw, I tried in a world that was created in 1.16 so that it's made in 1.15 is not the problem.

I don't know where to check that, but as I said the mobs and biomes I have left are the new ones added in 1.16 and none of them is counted
Please use a program like NBTExplorer to have a look, or attach your files containing the advancements.
Why do you wan't my advancement files? On a world that I just created(meaning the advancement folder is empty) it doesn't work either.
Check your playerfile to see which monsters and biomes you are missing, then kill/explore them and see if you get the advancement.
