Horizontal Ray color

Hi Online Forex Tester, I have a four-chart setup and noticed that when I place a horizontal ray on one of the charts and then change the color of the ray via settings, the new color does not reflect on the other charts and has to be manually updated. When changing the color of the ray on one chart, I would expect the color change to automatically update on the other charts as well, which does appear to be happening for the horizontal line.
