Same indicator: can not change color

[M_j]

hi all,

Maybe someone of you can help me with a small issue.

I add sometimes similar indicators to one chart.

I have noticed if I use same settings but only want to change the colour or the width of one - the second indicator window changes similar.

This happens in many indicators.

e.g.

The original: Stochastic Oscillator  - if I put twice the same settings and change only the colour of one it works fine.

ERROR Example: if one uses the Stochastic under Example one can not change the colour. 

Any idea - see attached picture
