Rule in PCB

[Hung]

Hi all
I'm setting Differential rule in Differential Pairs Editor but when I rebuild my project from SCH, my setting was canceled
How can I save it?
thanks you

Note: Normally I set differential pairs in Schematic.

Answer:
If you change or set some properties in PCB and you would like to keep them when you sync schematic, then go to Project -> Project Options -> ECO Generation and you may want to set some of the things to Ignore (these things will be ignored when you will be transferring your Schematic into PCB):
