moving duplicated tracks = wrong order

Hi,

i have track A and track B
i select both tracks and “duplicate tracks”
now i have
A
A (D)
B
B (D)

if i select duplicated tracks and move them UP i get :
A(D)
B(D)
A
B

but if i move those tracks down (wich i ALWAYS do because logicaly… sessions are left to right top to bottom correct ?) then i have invertion on A(D) and B(D) :
A
B
B(D)
A(D)

request : why not having order respected when moving multiple duplicated tracks down like it is up.
