Transceiver interface

[N9RU]

I must be missing a step.  I have two Flex radios on my network.  They each have fixed IP addresses.
When I enter both radios in the transceiver interface, everything looks good. However, when I try to change radios, i see that both IP address are the same now.  Whenever I change one IP address, the other one changes to that address also.I  can work around it by just putting in the correct IP for the radio I want to use  and clicking Start,  But the other radios address will also change.  Not big deal but i feel like I am doing not something to set the address right.
Thanks for any ideas.
