Cross references does't work after copy or linked copy

I created two page Page A and Page W at home level:
created two subpages for page A :(page B and page C)
my page C has a bixtext with 2 url (one to his brother : page B and and on other one to page W )
Created a linked copy of my page A, in the destination the url in sub page C are not corrected , both of them point to the home page
The same for Copy normal
