WPF PieChart DataLabels and Colors Disappear after Series Update (via Timer or Refresh)

[e11303]

When I update my PieChart.Series in WPF (LiveCharts2 v2.0.0, .NET 8.0, OS: Windows 11), either by timer or manually refreshing, the PieChart loses its DataLabels and resets colors to default after the second or subsequent update.
This happens even if I assign a new array of PieSeries, and sometimes the chart only shows the percentage labels on the first render.

XAML:
<lvc:PieChart
x:Name="PieChartControl"
Series="{Binding PieSeries}"
LegendPosition="Bottom"
Height="300" Width="350"/>

C#:
private ISeries[] _pieSeries;
public ISeries[] PieSeries
{
get => _pieSeries;
set { _pieSeries = value; OnPropertyChanged(nameof(PieSeries)); }
}
// Timer every 1 minute:
PieSeries = Array.Empty();
PieSeries = pieData.Select(item => new PieSeries
{
Values = new double[] { item.Percent },
Name = item.Name,
DataLabelsPaint = WhitePaint,
DataLabelsPosition = PolarLabelsPosition.Middle,
DataLabelsFormatter = p => $"{item.Percent:F1}%",
ToolTipLabelFormatter = p => $"{item.Percent:F2}%"
}).ToArray();
OnPropertyChanged(nameof(PieSeries));
PieChartControl?.Invalidate(); // optional, does not fix the problem

I would greatly appreciate any guidance on how to resolve this issue, or if there is an official workaround available. Thank you for your support and for maintaining such an excellent charting library!
