How can add new plotBand to gauge type of highchart?

I have used the following JSFIDDLE gauge chart. I am looking for to add new plotBand at spesific range of (from ,to).

But, when i add new plotBand, by the followind command:

chart.yAxis[0].addPlotBand({
                from: 0,
                to: 100,
                color: "#E0E0E0",
                thickness: "10%",
            });

the new added plotBand does not completely cover the old plotBand and the old one’s border is visible!. How can hide completely the old one?
I must say that, using addPlotBand function is my only approach to add plotband.
