I was trying to set up something in “wake on lan” tab in networking and it will not take or keep the IP address properly.  Is this tab no longer supported? It seems broken.

WoL does not use a device's  IP address. When you suggest an IP address, ISY uses it to generate the highest address on the subnet and use that which is assumed to be the WoL IP address. Then the MAC address is sent a WoL packet using that address.
If you use two subnets allowing 511 addresses it will be hard to make work properly and address in the lower subnet will not be woken up using this WoL tachnique.

eg: WoL 192.168.0.67. =  ISY uses 192.168.0.255 and the MAC address for that device. All devices hear this on the LAN but only the specific MAC device uses it and wakes up it's device.

I think you meant 192.168.0.255
