Virtual Led help

Having an issue getting the virtual led feature to work. Both boards are ESP8266 (just trying to use up my surplus on smaller projects) with one driving a strip of 56, and the other a strip of 48 pixels. When ever I set one of the boards to the DDP RGB network with the masters IP I loose control over the master board. When I log into the master interface, and make a change only the slave board changes. I’ve tried rebooting (unplugging from power), and flip/flopping the master/slave, but the problem just follows the master. The SYNC tab on the interface doesn’t seem to do anything.
