Hello, I have a line chart where I added the average and standard deviation reference lines to the x-axis as well as a number of reference lines to the y-axis. When I add another measure and create a dual axis, the reference lines all remain in place (Capture1.png attachment). When I remove the dual axis, the reference lines all remain place (Capture2.png attachment). However, when I drag the second measure off the "Rows" bar, all axis lines disappear (Capture3.png attachment). This doesn't seem logical as the reference lines should stay in place since I created them on the first measure and NOT the second measure that I am trying to remove. Can anyone find a workaround for this? Thanks.
