Perspective XY Chart, 2 y-axes , 2 lines, 2 columns (opposite y-axis) issue

Has anyone encountered an issue in perspective xy chart when there are 2 series that is using the opposite y-axis? Please see attached photos. m3_order_line_actual is using "m3_order" y-axis which is set as opposite=true but it is not using the opposite y-axis. From memory this wasn't a problem last year (if i can remember it right) but it is an issue now.
