How to turn off logging for Rule 0 - Invalid Traffic

Question

Hi, Sorry if this is a stupid question. I am getting a ridiculous amount of "Invalid Traffic" thrown by the Firewall Rule 0 with the message "Could not associate packet to any connection" There is an old article which references this and says the logging can be turned off but it doesnt specifically state how to do this and i can't find a setting for it anywhere. I have other things i'm working on and really want to turn this off. Is anyone able to assist me? 
 Many Thanks! Martin

You can generally deactivate this logging for invalid traffic (my personal way to go) on Log settings. 
 Or you could increase the timeout of conntrack and there should be "less" invalid traffic.
