Foreman-installer option on smartproxies to enable puppet reports

The hosts managed by smartproxies don’t send puppet reports to foreman server. I m using Foreman 1.19/Katello 3.8. On smartproxies, after foreman-installer is run (with the scenario foreman-proxy-content) the puppet.conf file have the option reports = store.

When I run foreman-installer --full-help, I see
--puppet-server-reports List of report types to include on the puppetmaster (current: "foreman")

Did I forgot to do something at setup ? Should I fill a bug report ?

Foreman and Proxy versions:
Foreman 1.19-RC1/Katello 3.8-RC1
