Library editor bug - multil unit part pin positioning

When make multi unit part,

I sort and position pin in unit B.

next, I move some pin in unit C.

But It cause move some pin in unit C.

somebody can help me?

hm…
toggle “Edit pins per part or body style”, do not cause that other unit move.

but, before toggle “edit pins~~~” why some pin cause, the others pin not cause?

Have you tried to toggle the ‘All units are not interchangeable’ option in the symbol properties dialog?

…and/or for the pins the ‘Common to all units’ option?
