If I append new DKIM record in the admin area the new record is broken (vim with :set list):
; Add additional settings below this linedefault._domainkey 14400 IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCaJKTJvtbkUfGopmttOJc/9KcHOhpu000iPYzeBscEdHFWbCUM+9kFGPxkq8CxFLDWlyzPKbdhWz8eKNy39JlSDOzM6e+yZfLmZ7QBuoMuycAVP2/5wVf15QrhRYk7K9jdTzuXGHoHJnlXYOxECKufHD8uIorHhkYADHura5RvjwIDAQAB"$
The problem is there no new line after the ; Add additional settings below this line or before the new DKIM record. If I append new record everything looks like normal:
