MCCC Alien-ize Sim Cheat? Buggy Disguises?

So I'm trying to alienize my sim and have the current human sim I'm alienizing be their disguise. I used mc command centre and it worked but it appears the disguise self option is buggy? Like there is no option to do it unless you go into the mccc menu? Is this normal?

Anyone know any other mods that would help me do what I'm trying to do?
