The bottom one I think.

The collection you mentions seem fine for me, but I just gave them a quick test.

Have you perhaps expanded the collection in the symbol catalog window? If you expand the collection (+-sign), and then pick a symbol from the expanded view, CC3+ takes this as a sign that you want full manual control over the process. and stops doing random picks.

The reason the drawing tools all seem to use the same fill is because they are looking for a fill that does not exist in the current map, so they fall back to the currently selected fill instead. This is an indication that your style isn't set correctly, since each style typically have it's own fills.

To get the tools showing the proper fills (for the style they belong to), you can import the fills into your map using the procedure described here (but I do suspect that isn't really what you need here, you probably wish to use the correct tools, not the correct fills from the wrong tools.):

Final map for the Dunor Valley. With these Quenten has mapped the entire valley in a grid of maps in the Local Area Style. 26 maps in all.

Now in the atlas. Thanks Quenten.
