problem configuring XB24-ZB in Api Mode

hi everyone,

i am trying to use two Xbees,one coordinator api and one router api and trasfering data between them.
But when i try to make the settings through the X-CTU at the router i face a problem,I set the pan id as 1234 but the OP-operating Pan id line remains at 0,the OI-perating 16-bit pan id line remains at FFFF and the MY--16 bit Network address remains at FFFE.As for setting the coordinator i didn't have any problem and i tried with any of the xbees i have but nothing.
I am using arduino uno,wireless sd shield and xbee s2
Here is a screenshot attached:

plz help me.Thanks in advance!
