I need assistance acquiring my maps, please.

I hit "Download Map Packs". Then I select "All Maps" and before I hit the download button... Towards the bottom of the screen it mentions that Each pack contains 3 layers for each map:
Layer 1: The map lines
Layer 2: The points
Layer 3: Grid lines

After downloading and extracting, I notice that I am only given the first 2 layers.

How do get all the "Layer 3" maps without having to tediously search through each and every single map file? Didn't there used to be a one-stop quick hit button for this?

Additionally, I would also like to get all the primary "Combined Map" layers, again, without having to methodically search through each and every single map file.
