change RefDes in schematic causes changes in pcb routing

Good day every one!

i use  Allegro CIS  & PCB 16.6

I have complex hierarchical design  divided into several pages. Each pages included couple of several logically separate circuits. I want to move some of  those circuits to another page for better readability of the whole schematic document.

Copy - delete - paste to another page should solve the problem BUT the problem is that I already have routed design. And any refdes changes from CIS after creating netlist and update brd file caused moving connetions and etch removing.

Actually parts are not moving - it moving connections from them - see picture.

For example i rename  two parts in schematic R3 -> R4 . Then Tools ->  Create netlist (with option of update board file) -> after netrev it open brd file and see that refdes of the part dint change their old places , so all old clines will be lost.

Options->Preferences->Miscellaneous->Preserve reference on copy did not help,  maybe because i have   more than one hierarchical blocks in schematic/

See pictures with changes and settings  below

So my goal is to change refdes`s of components  from schematic WITHOUT  ANY changes of routing in brd - how i can do that ?
