Template headers repeated

[dsnt02518]

I'm seeing the _header.erb contents included twice in /etc/freshclam.conf and /etc/sysconfig/freshclam.
I think the problem stems from using ERB.new(...).result(binding) to render the included template directly, instead of scope.function_template(...).

The problem only seems to occur when applying via puppet agent, for some reason using puppet apply on the same catalog doesn't include the header twice.

I've locally found that the replacing the call as in the diff below gets identical and correct behaviour with both puppet apply and puppet agent:

Should have mentioned - I'm using puppet version 6.19.1 on CentOS 7.9, apologies!
