Can't change Meter Color Preference

About 6 months ago I discovered I could change the color of the meters in edit- preferences- metering- appearance.
It worked for me then.
Now I am trying to change them again but the change won’t apply.
Anyone know what I’m missing?


It works to me here in Cubase 10.0.50 on macOS.

Did you click Apply button? Could you attach a screenshot, please?
