timer ( cron:* * 10-18 * * ? ) rule consequences output duplicated

问题

I want to limit the rule run in a specfic time span ,the rule i wrote is as below

rule "Event3"
    timer ( cron:* * 10-18 * * ? )
    no-loop
    when
        $m : EventTest( originNumber == "123", originNumber : originNumber )  from entry-point "ATM Stream"
        or
        $m : EventTest( originNumber == "456",originNumber : originNumber )  from entry-point "ATM Stream"
    then
        System.out.println( $m.getOriginNumber() );
end

when i insert a new fact into engine,every inserted fact before will duplicated triger the rule,how can i forbiden the have existed facts triger the rule?

the output log is below
