The default dummy from Roblox studio's built in plugin won't break the joints on death, nor respond to gravity

I used the “Build a Rig” built in plugin, and added a block r15. I have break joints on death set to true, and all body parts are not anchored, but when it’s health reaches 0 it won’t break the joints, and if I set its CFrame to something above the ground it won’t come down.

Should I insert characters a different way, or am I doing something wrong?
