How do I prevent Mezzmo picking up files in my "1000 Most recently Added" folder?

The items in "macclesfield houses" keep apearing in both "1000 Most recently Added" *and "RANDOM 5000 Photos". I've tried dragging and dropping "macclesfield houses" into the route folder "Library", but still the contents appear in recently added and random.
