Fatal error when trying to enable demo mode

Hello, I just installed cPanel on a new VPS and I just noticed that I am unable to activate demo mode on any account. cPanel 11.60.0.46, CentOS 6.9

[2017-09-01 14:41:33 -0500] die [Internal Death while parsing [stdin] 3382] invalid group name specified: cpaneldemo at whostmgr/bin/whostmgr.pl line 1839.

I have setup thousands of servers before and have never seen such thing. there is no cpaneldemo on /etc/group. I am wondering if I add this group maybe demo mode would work ? But why is there no cpaneldemo group after installation ? Everything else looks fine...

I was able to enable demo mode on an user after manually creating the group 'cpaneldemo'. But I still wonder what went wrong that this group wasn't created before or if I am breaking anything by manually creathing the group...

Hello, Here's an example of the default entry for "cpaneldemo" in the /etc/group file:

# grep demo /etc/group
cpaneldemo:x:1002:

I'm unable to reproduce this issue on a test system. Can you verify if you see any error messages in /var/log/cpanel-install.log related to the /etc/group file? Thank you.
