Achivments on switch not working

so i had 100% of achievments before 1.18. i wanted to get back to 100% of achievments and i started with caves and cliffs (freefall from y=320 to bedrock). so i did and it wouldn't register. i watched tutorials on if it had to be 64 or just bedrock and they landed on 60 and it worked, but it was a little delayed. for me, i wated 10 minutes and nothing happened. i also landed on y=-60. unless it's because i was on an existing world or what, please fix this.
