Changing color of a joined track is buggy

Bug 1: BG Color can be changed from the right click menu but not from Background box in graph adjuster tab.

Bug 2: FG color changed using the box in graph adjuster, changes both the label and the lines, but using the right click menu only changes color of the label. There is no way to change line color from right click menu.

Ideally, both the box and the menu for BG color should change BG color. The box and the right click menu for FG color should change both the label and the lines.
