Can not reuse static IP addresses - firmware bug? (Fixed - read reply)

I use static IP address for my devices.
Occasionally I will change an assigned address as my network changes. The problem occurs when I delete an assigned address. In most cases, the device will drop from the tab entitled 'Address Reservation' but it will still show up on the tab entitled 'DHCP Client List' labeled as 'permanent' and showing the former static IP address. This happens even when the device is no longer attached to the network and hasn't been attached for weeks.
If I try to reuse the IP address for a different device, I get an error message from the router that says the address is still assigned. I can wait until long past the IP DHCP refresh time and it still chokes up.
The end result is I can't reuse an IP address that was once assigned permanently to a device but now that device is long gone.
Is there a work-around or is this a bug in the firmware? The network has about 30 devices.
I have used assigned, static IP addresses for years with no previous problem. The ER605 is new to me. I used pfSense untii recently and like this router more. Some of the features that made pfSense attractive years ago are either now included in the ER605 or I no longer use those features. However, this problem is a show stopper as my numbering system has a pattern and the ER605 is slowly causing me to run out of IP addresses.
