Block fragmented IP datagrams was disabled by itself

After I install Comodo, I always check all of the boxes off in the firewall configuration for maximum security. Today i noticed that the something changed my firewall settings and the box to block IP fragments was unchecked.

I browsed through the firewall logs for the past month in the log viewer and didn’t see any changes to the firewall settings.

Just an idea, been testing Comodo on several machines lately.
The Advanced options are always disabled by default.
Did you update Comodo firewall lately? Maybe the options were reset during the update.
