Hierachy makes child elements disappear

When I add a legs under the body, the legs disappear and they are nowhere to be seen. I have tried to “bump” the leg forward in the Z axis, but this does not fix the problem of the disappearing element. Removing the element from the hierarchy brings the element back.

Help please!

What do you see in the Network window before and after moving the legs?

I just had to disconnect the character group from the composite:)
