CoreChart throws "Core not set yet" exception when I try to ClearCrosshair in CartesianChart.XAxes

[sardo75]

Hello, In my code I have a CartesianChart (LiveChartsCore.SkiaSharpView.WPF 2.0.0-rc5.4) called "graphic". I show a Crosshair in X axis by setting it properties CrosshairLabelsBackground,CrosshairLabelsPaint,CrosshairPaint....When i try to hide the Crosshair, setting those properties to null, the chart remains with the Crosshair, and I try to remove it using ClearCrosshair(graphic.CoreChart) in the axis, but it throws a "Core not set yet." exception...could someone help me?

I noticed that Crosshair is stacking and it's not removed if I set axis multiples times with Crosshair formatting for example:
CartesianChart1.XAxes = {xAxis}
CartesianChart1.YAxes = yAxesList
So every time I set axis, it leaves instance of crosshair paint in the background. Assuming you would set axis 100 times, it would paint crosshair 100 times.
I wonder what else is left behind...
