Scoreboard Parameters Don't work properly

the command I am trying to run is this
/execute @e[score_Test_min=1,score_Test=1] ~ ~ ~ setblock ~ ~ ~ sand

when I get rid of 'score_Test_min=1' it works just fine. I have tried this with multiple other commands and it still seems to be the case. I have checked to make sure the scores are being set and they are.
