Curse of Strahd module, players cannot see where they have been

Hey guys, I'm trying to make the QoL for my players abit better by having the grid where they have been appear but i can't seem to get it to happen. All their tokens have "has sight" selected and "All players see light" selected as well. We have a game scheduled for two hours from now and I really thought I'd be able to plug n play this and figure it out but I don't know Roll20 well enough to go further than i have. I've attached a picture of the page settings.

I don't think advanced fog of war ever got fixed.  I use very dim torches that are set to controlled by all players and with sight. The token is a transparent png with a 0 foot aura only I see. Drop these behind the players when they move on from an area.  It's a wonky work around but it has the desired result.
