[Solved]-Highcharts: duplicate datalabel text on export-Highcharts

This is what worked for me. I disabled the textShadow inside the series

series: [
        {
         name:'Serie1',
         data:[2027.15, 2027.15, 0.0], 
         dataLabels:{
                enabled: true, 
                style: {textShadow: 'none'
                }
        }
    ]

This looks like a new problem in the export service.

I was able to work around it by disabling text shadows on the data labels. To do this, I added:

dataLabels: {
    style: {
        textShadow: ''
    }
}
