The Evoker doesnt turn blue sheeps to red if commands are running on this world

I saw in a video that the Evoker is suppost to turn blue sheeps to red. but when I tried it in my main minecraft world it didnt work. (I got commands running on this world) but when I tried it in a world with no commands running it worked just fine. to test if its all because of the commands running I tried it in another world with commands running and it didnt work again.

so Im 90% sure that its the commands fault but Im not 100% sure,,,
