Unity 4.1.

Under subscriber...caller input programming.

On Key 1 I program for alternate contact number ex:7777

Then

On Key 2 I program for alternate contact number ex:8888

For some reason when i go back and check Key 1, the alternate contact number changed from what I programmed 7777 to what I programmed for Key 2 8888.  The system will not allow me to apply 2 different alternate contact numbers. 

Is there a setting or restriction that I am unaware of?

Thanks!
