PivotGridFieldList Row Filter causes null exception when underlying filter data has null values

[Patrick]

Using 2024.1.423 PivotGrid and PivotGridFieldList, when trying to do a row filter on a column that has null values, Telerik.Windows.Controls.FieldList.Editing.Selectable.GetHashCode() will error with a NullReferenceException.  This works when doing a label filter on a row or column though since the pivotgrid and the PivotGridFieldList use different methods of getting the distinct values.

Any way to fix it without having to modify the underlying data?

Thanks,

Patrick
