The issue is not solved.  You still have something that adds the
bogus values before the reinitialisation.  Whether this has some
adverse effects depends on the scripts.  (Sample script attached).
Basically you probably do ~ this:

  init_main
  # ...
  main=($main)           <-- Creates extra values
  # ...
  init_main
  printf "%-20s %s\n" ${(kv)main}

This is a bug in your scripts and not in zsh.

Forget about the typeset, look for "main=$(main)" or similar.

init_main
main=($main)

printf "%-20s %s\n" ${(kv)main}
