Bind9.16 zone SOA record issue.

[Thomas Strike]

I've been pounding my head over this issue all day with no results.

I am hosting Bind9.16 on a Ubuntu 20.04 server.

I have several zone records that report the same problem but I also have 
several zoned that are configured with this same template and run okay 
on the server. I've surfed the Internet for any clues and tried 
everything I can think of but cannot get rid of this problem.
I really would appreciate any help I can get.

When I run named-checkzone I get 'unknown RR type 'ancienttom.us.'

My named.log shows;
