DNS server failed to load

hello,

i am having issues with dns server , its giving following error while loading. kindly suggest how to fix these errors.

there are two main errors i see due to which dns server is not loading the zone file.

/var/named/esoftware.pk.db:36: file does not end with newline

what does this means? and how to end with newline?

zone esoftware.pk/IN: has no NS records

when i try to add NS record in dns zone file it gives error , (there is some error with configuration, please check and update)

also i am not able to add A record for ns1 and ns2 to point to my server IP

Simply modify that file, add a new line at the end "Press enter" and save, restart the DNS server and it should work.
