Change template to child-ns problem

[morcom]

My last 2 domains are working well and I had no problem with setting up.
However just started on my new domain -
1. Add domain yourdomain.com (leave DNS Support mark checked) - completed ok
2. Go to DNS menu - ok
3. Click on edit under yourdomain.com - ok
4. Change template to child-ns - problem as I have no box "change template"??

If I check my previous sites DNS menus there is now no box to change the template. It's as if this function has disappeared?

Any help gratefully appreciated

I have just rolled back 24 hours on the server (digitalocean) and it looks like the problem is not there now.
On reflecting I remembered that I did update the core yesterday and all looked ok afterwards
outdated vesta core package Version: 0.9.8 (amd64) Release: 8

Could the update have caused the problem? I'll wait awhile till I try it again.....

NO.... still the same but realize that with ADMIN user it's available and other users not available for existing domains??
Seem to be going round in circles here
