AC Grasshopper Object Hotspot problem

[RhinoX]

Dear Forum,

I know that here are a lot of expert GDL, I want to ask a simple question that I can not solve it..

I only want to rotate the block (Archicad object) via the axis in the center of the block, but in AC always rotate that in the corner.

I have moved the hotspot but the same result, no change. I tried many ways but still got the same result, too difficult.

Can anyone give me some advice for that case? Thanks.

I attached some photos here.
