Foreman-proxy start error on installation - katello install

Problem:
I’m running an install where I explicit exclude the foreman proxy. However the installer still attempts to start it causing an error/failure.

foreman-installer --scenario katello \
                  --no-enable-puppet \
                  --puppet-server=false \
                  --foreman-proxy-puppetca=false \
                  --foreman-proxy-manage-puppet-group=false \
                  --foreman-proxy-content-puppet=false \
                  --foreman-proxy-puppet=false \
                  --no-enable-foreman-plugin-bootdisk \
                  --no-enable-foreman-proxy \
                  --enable-foreman-plugin-memcache \
                  --foreman-plugin-memcache-hosts=mem.fqdn \
                  --foreman-foreman-url=http://foreman.fdqn \
                  --foreman-initial-organization=example \
                  --foreman-initial-location=US \
                  --foreman-initial-admin-password=password \

Expected outcome:
Installation error free
smart proxy does not start
