I defeated the final BOSS, The Radiance, and it was three times.
It should be three achievements.
but there is no note that complete the achievements?
Moreover, I have beaten the front two doors of God Home.
I should have made two achievements.
Similarly, I haven't received any notice that I have completed my achievements
Could someone tell me what to do?
:)

Check your achievements list in the main menu. If it appears empty, then it's broken. All achievements have issues since last major update, the bug was never fixed, and I honestly doubt they ever will.
