Hi Mustafa,
After I made an update of today's kloxomr 6.5.0f-2014041801, and executed cleanup, the dnstemplate and clienttemplate table got emptied!
I am sure that there were dnstemplates in there because before running the update I made a backup with Navicat. When I found that named did not start and gave errors, I investigated and found dnstemplate empty!
I am not sure about clienttemplate, though.
There was something in the last one or two updates in this area that has caused this change.
