You have Global Illumination enabled. That is telling the system that everything it lit up like the outdoors. Try disabling that option. You will also need to provide the distance the token can see in the Emits Light options, imagine like the token is carrying a torch or with Darkvision. I personally wouldn't use the Advanced Fog of War distance option on the token. My understanding is that it doesn't work correctly. You may want to use the GM layer for anything the token is not meant to see until it reaches a certain distance. Sure, a bit more manual work but it works more consistently.
