Firewall Log deactivated with CIS 4

I recently installed CIS 4 and was very worried because Firewall log remained empty.
I posted another thread about this (;msg403305#msg403305)
I received no solution there but discovered today that you have to activate it. It seems to be deactivated on custom installation.
For those that have the same problem : (I am translating the steps from Dutch so maybe it is different on your pc):
Comodo>Firewall>Advanced tasks>Networki rules>Tab Global rules>
Rule : Blok IP > Change
Here you can activate logging
In my humble opinion this option should be easier to reach. I would expect this in Firewall behaviour rules.
