How did you try to delete this zone?  Using samba-tool dns zonedelete or
using ldbdel?  If you tried to delete using "samba-tool dns zonedelete" it
would remove only one of the zones from DomainDNsZones partition and not
from ForestDnsZones partition.  The correct way would be to delete using
ldbdel.

   ldbdel -H /path/to/sam/database  DC=taylortelephone.com
,CN=MicrosoftDNS,DC=ForestDnsZones,DC=taylortelephone,DC=com
