score_min argument not working

Used the command

scoreboard players set @p[x=-8,y=21,z=5,r=1,score_Kills_min=250,team=Rank2] TP 1

scoreboard players set @p[x=-8,y=21,z=5,r=1,score_Kills_min=250,team=Rank2] TP 1

I am neither on Rank2 team nor do I have 250 Kills But it stated it is giving me one TP point.
