I tore my old tank down and started a new build. I did a factory reset on my apex as I was having issues setting up. everything is working just fine now except my VDM module has a green status light and the light turns on and off randomly on it's own. When I search my module on the classic dashboard it says OLD. My powerheads that are connected to the VDM show on my dashboard but I cannot control them. Any ideas I have tried using different aqua bus cables and different ports and I did update the module with no change.
