Vet cut kittens claws abnormally short after neutering surgery. Is this normal??

We just had our kitten neutered yesterday and found today that they cut his claws what we think is abnormally short over half his claw is gone in some cases. We normally just cut the tips off. Do we just leave his nails long normally or did they cut them abnormally short??

Thanks for the help this is my first kitten.
