C4D- Rigging R21.207 / Character won't move with the rig


Hey people

I’m still learning Cinema 4D and I tried to do a simple rig constellation. Well, my Character won’t move with the rig, just the ghost is movable in this combination. Thought it could be a bug of the Weight Expression Tag, but it didn’t changed anything when I rebuild it again. (and again)
Anyone that has the same problem or a mind blowing tip for me?

I searched the www but cannot find the right solution.

Would love to hear your recommendations or tips how to do this specific thing or get better in rigging.

Thanks a lot, xo
