DDR3 IO pins changing in .xdc file

Hi,

I'm using zc706 board, In that i used DDR3 IP core without using PS. I have created the IP core and copied the IO information form example design in to my top_level design xdc file. this information changes some times. the port pin number is deleting in my top_level desing xdc file.  My clock and dqs pin are removing. Anyone help me to solve this problem.
