samba - May 2021 - Reverse Lookup Zone Not Loaded by DNS Server

I have a samba AD domain based on two DCs running samba version 4.14.4 on Debian
Buster.    The domain is using Bind DLZ.   When I
open DNS Manager on a Windows domain client both the forward and reverse zones
are shown, but if I press F5 and click refresh the
reverse zone shows a red X and the error: Zone Not Loaded by DNS Server.   The
zone info looks normal:

samba-tool dns zoneinfo tiger-db 2.168.192.in-addr.arpa -U roy

  pszZoneName                 : 2.168.192.in-addr.arpa

  pwszZoneDn                  :

  dwLastSuccessfulXfr         : 0
  fQueuedForBackgroundLoad    : FALSE
  fBackgroundLoadInProgress   : FALSE
  fReadOnlyZone               : FALSE
  dwLastXfrAttempt            : 0
  dwLastXfrResult             : 0

Any idea how to debug this will be appreciated.

Thanks

Verify if this is set in bind9. 

# /etc/systemd/system/bind9.service.d/override.conf
[Service]
# Disable reloading completely.
ExecReload# Or set it to restart
#ExecReload#ExecReload=/usr/sbin/rndc restart

systemctl daemon-reload
reboot server,.
