Dont think so, try to relog if u didnt yet. Also your lvl might be too low, but I dont know the required lvl for it.
Include you nick and world in case sth would get bugged
i have catch 140 and too nothing receveid archievement I know it's sad kkk
then returning to the subject I spoke with a tutor in the game he told me with the arrival of various new pokemons entered hoen and the archievements of it catchs as dex were exceeded and there are many more easy the catch then increased the amount required for each archievement that's all I know I hope I helped (^_^)
