Can you share the FCW file so we can have a look at the grid setup?

You're welcome :)

Profantasy also has a channel full of Live Mapping sessions which Remy has indexed on this page of collected tutorials if you are interested:

If you have the Tome of Ultimate Mapping, lighting is covered from page 279 under the title "Lighted Dungeons"

Alternatively, there are a couple of Live Mapping sessions you might be interested in here:

At the present time there isn't a way of transferring the settings themselves to VTTs. Any lighting you add to your CC3 map will show in the exported image and be fixed as part of the image.

That's just the recording that Remy uses before the real start of the stream ;)

You're welcome :)

Don't forget to switch that radio button back to Selected Sheet before you move on with the map.
