There were many small composites < 10^18 (from a bug) in Oct 2021, and all of them had been deleted, but there were also many small primes < 10^18, also from the same bug, but why they have not been deleted? I think they also need to be deleted.

Along with deleting those bad primes, please just delete/disable the modulo operator altogether if that hasn't been done already. It obviously isn't implemented correctly, it's not particularly useful, and tons of bogus data has resulted from its use.
