FIX: Perfect Server Automated ISPConfig 3 Installation [UFW won't update]

Hello Community,
We just came across a small bug in the tutorial here:
https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/#-setting-up-the-firewall

Actually the ports are already pre-populated so if you just click "Save", it is saved but not applied.
If you do: #ufw status it shows:

The fix here would be to do #ufw reload or to #reboot the server.
It should probably be mentioned in the tutorial unless the ISPConfig itself cannot call the ufw reload.

Small bug #2:
If you choose a custom port for ssh during installation ie. wget -O - https://get.ispconfig.org | sh -s -- --ssh-port=12322
it does not pre-populate in the Firewall section mentioned above.

Small bug #3:
The custom ssh port is also not reflected in the fail2ban config: /etc/fail2ban/jail.local
