A bar or column chart without a category having multiple values still group values over a category

Have a Bar or Column chart with multiple values, and without a field on Categories. Note the position of the bars as though there were a field on Categories while still listing the Value title on the axis. For example, in the Sample ECommerse widget, the United States value bar is above the axis label, the United Kingdom bar is centered with its axis label, and the Australia bar is positioned below its axis label. The bars are also positioned and narrowed to leave space for all values over each value. But never will more than one value render over any given axis label.

Add Age Range or something on Categories and note the grouping of the values as expected.

What I would expect in the first scenario without a field on Categories is what I experience in Sisense on Windows. Each value is aligned with its axis label. The bars are also thicker because they are not reserving space for two other bars over each label.
