Well, I just did a factory reset via the menu, and it ended up on V2.01.03 with a VM SSID.
So then I tried a pinhole reset and it reloaded V2.01.03, the VM SSID is still there. Could it be that V2.01.03 is now the default?
As it happens it isn't causing any problems at all for me and the range and speed is fine, I just wanted it back the way it was
I will keep an eye on it.
