VTFL copy control settings not visible

hi

i am facing some problem in copy control settings - vtfl - delivery to billing type copy control

when i am doing the required settings i.e copying ZLLZ delivery to ZFD billing type and saving the settings, a transport request is being generated and also it says tht data has been saved,but when i see the list i cannot see the new copy control tht i did.

i can see these entries in the table TVCPF. but these entries shows billing type ZFD n delivery type ZLLZ

along with additional entry in sales doc column as "ED"

i am not able to understand from where this entry is being picked...

an why i cant see the entries at VTFL

can anyone help.
