In the first attached screenshot, I have 6 BarSeries (all with the same values for the data).  5 series are stacked in 2 groups (using the stack key). The sixth series has a combine mode of Clustered.   You can see where the Clustered series is much wider than the stacked series.  In the second screenshot, I have 3 BarSeries. 2 are Clustered and 1 is Stacked. In this case, the Stacked BarSeries is the one that is wider than the other series.  I am using a point template for BarSeries, but it is not doing anything with the width (It's a Border).  Is the width difference purposeful, or is this a bug?
