DHCP Static mapping not showing IP for my device

[lanlubber]

Ok, so I clicked on one of my dhcp leases to make it static.  The instructions say if I leave the IP field blank it will assign from the pool, great.  However under Services - DHCP at the bottom of the page shouldn't the Static Mappings table show the current assigned IP in the IP Address field?  The IP Address field is blank.  I was hoping to use the Static mappings table as a nice view to see MAC, IP and my entered description since depending on the device hostname is pretty worthless as a description field.

Thanks
