[Solved]-Remove SVG rendered path on Legend Item Click-Highcharts

You don't need to remove the custom arrows, it is enough if you update their positions. For example:

if (series.customArrow) {
  series.customArrow.attr({
    d: path
  })
} else {
  series.customArrow = series.chart.renderer.path(path)
    .attr({
      fill: series.color
    })
    .add(series.group);
}
