New to Dynamic Lighting, running into problem setting up characters

Hi, Setting up the party for "Lost mines of Phandalver" and really don't understand where I'm going wrong with Dynamic Lighting. This is what one of my PCs (no darkvision, global illumination disabled, no other light sources, all I've clicked on the token is "has sight"). I've taken this screenshot from an incognito chrome page with a second account controlling the character. The same thing happens when I press CTRL+L from the DM perspective. He seems to be completely ignoring the dynamic lighting nd I don't understand why. The other four characters have worked out fine but this one is different somehow. I've just tried it on a different map and there were no issues. Any help would be amazing thanks

Actually, it's not true that he's ignoring the dynamic lighting. He still can't see tokens hidden by line of sight. When I put a light source outside the cave his vision changes (see below). He also cannot move through the lines chalked out by dynamic lighting.

It would be helpful to post the token settings (both tabs) and the page settings, showing the DL section.

Best guess, it sounds like he has no light source to see by. For him to see anything, he needs a light source, whether from himself, or an external token with "Other Players see Light" clicked.

Thanks for the quick reply. With the othercharacters, as they have no light source to see by, their token are simply surrounded by black which is great. My concern is that this guy can see into the cave itself which the others can't and he certainly shouldn't be able to. In my first reply I've added light sources as you can see but he still has this super-human sight into the cave itself. As I say, the irritating thing is that it's just this token, just on this map. When I put this token on other maps it works as expected. Thanks - SS below as requested. 

Ah, now I understand the issue. You are using Advanced Fog of War. That token has been placed inside the dungeon and will "remember" the map, but not the tokens it has seen. Either turn off Advanced Fog of War, or choose reset fog from the Fog of War flyout menu on the toolbar. This will reset fog for all tokens on the map.

You are a legend thanks so much mate
