Same color for different values in donut chart

I have a donut chart and the values show different colors in the case of vehicle

When I change the chart column to location the three values all have the same color and any changes to colors affect all three values in this case.

Both columns are type=ref. Why is there only one color for the location column and why can’t I change it?

Please show the view definition for these two charts. Something isn’t configured right in the second Chart.

Ok, I’m using the same view and switch between ‘location’ and ‘vehicle’

Location…

results in

Vehicle…

results in
