Resources not appearing at certain scale


I have different scales setup, but my resources aren’t showing for the month level scale - as you can see I would expect there to be resource elements for ‘Search’ and ‘Television’ in October, but nothing is displaying.

                name: "month",
                scale_height: 50,
                min_column_width: 30,
                scales: [
                    { unit: "month", step: 1, date: "%M %Y" },
                    { unit: "day", step: 7, date: "%d" },
