When I try to change the color of an indicator, the program imposes the previous color saved from the previous indicator on the current one.

Example:  I have a MIMA17 that is purple.  I have a MIMA34 that is blue.

I change the MIMA17 from purple to orange using the "Line Properties" window. 

Then I click on the MIMA34 to change its properties.....and when I do this, the program changes it from blue to orange without any action by me.

The actual color blue should be what is presented in the "Line Properties" window...but instead, this window shows the last color that I changed to, which is orange.
