Pinned Visual Truncates X-Axis Data at Smaller Sizes?

I have a report that I have pinned a visual for to a dashboard.  The visual appears correct if the tile is 2x3 on the dashboard.  If I size the visualization down to a 2x2 tile, the x-axis is truncated and is missing the last two data points.  In the screenshot below, the 2x2 tile ends at datapoint 2018.41 ... if you stretch the visualization to 2x3, the visualization (correctly) ends at 2018.43

If you hover over the data lines in the 2x2 tile at the very end, it still ends at datapoint 2018.41.   If you click the tile and go directly to the report from either sizes, the actual report looks correct (it ends at x-axis data point 2018.43)
