Mismatch Coloring for Measurement on Line Chart

[qqlottelotte]

Hi everyone,

Would like to see if anyone face similar problem before:

Situation: 

Created a line chart as below with 10 master measurements each with different colors. The color areas can be displayed correctly when no filtering is made.

 

Problem:

However, when some of the measures are selected, the color of the area's outer line does not match with the color of its corresponding area.

For instance, below selected three measurements (light red, red and blue). As you can see, yellow appears in between red and blue which should be blue instead.

Below selected one measurement (green but red is wrongly shown)

Appreciated if there are any suggestions for investigations or solutions.
