You forgot for multi rounded maps to use:

{
        match:
        {
        "classname" "team_round_timer"
        }
        insert:
        {
        "On4MinRemain" "tf_gamerules,addblueteamrespawnwavetime,2,0,-1"
        "On3MinRemain" "tf_gamerules,addblueteamrespawnwavetime,2,0,-1"
        "On2MinRemain" "tf_gamerules,addblueteamrespawnwavetime,2,0,-1"
        "On4MinRemain" "tf_gamerules,addredteamrespawnwavetime,2,0,-1"
        "On3MinRemain" "tf_gamerules,addredteamrespawnwavetime,2,0,-1"
        "On2MinRemain" "tf_gamerules,addredteamrespawnwavetime,2,0,-1"
        "OnRoundStart" "tf_gamerules,setredteamrespawnwavetime,2,0,-1"
        "OnRoundStart" "tf_gamerules,setblueteamrespawnwavetime,2,0,-1"
        }
}
