I missed a "." while installing pihole on my Gold Plus.

So, trying to install PiHole on my Gold Plus and I missed the "." before the ".firewalla"   have I created a mess and if so, how do I undo it?

"/home/pi/.firewalla/run/docker/pi-hole/docker-compose.yaml"

Also is docker installed and running by default on the pihole because i see 2 containers?
