Seems to me that only the templates are limited and that you can add more rulesets.

Firewall templates

If you click on the “Firewall templates” button in the server overview (“Main functions; Servers”), you can create your own rulesets. Then you can paste these rules via the drop-down menu for the servers’ firewall configuration and configure them.

In addition, there are several pre-defined example templates for common server services by default.

this will allow me to add more than 10 rules? my problem its that i can add only 10 cloudflare ips and i want 4 more and 1 rules to close all connections so i want 15 rules… and i got only 10

I am not a Hetzner customer but regarding to their wiki it seems that one ruleset / template is limited to 10 entries. Try to create a new custom one. Either you are able to use more than 10 entries or just add the remaining four net ranges to this new set
