[BUG] RadzenDataFilter does not produce expected LogicalFilterOperator via Filters property

Single-page set up

    public class DebugSample
    {

        public decimal Latitude { get; set; }
    }
}

Reproduced on both complex and flat objects

Wire up the page, set values for both filters as on the screenshot

Notice usage of the 'Or' operator

Click both buttons, observe correct value from ToFilterString() and incorrect value from Filters

Click Composite

[
    {
        "Property": "Sample.Longtitute",
        "FilterValue": 1,
        "FilterOperator": 0,
        "LogicalFilterOperator": 0, // expected 1
        "Filters": null
    },
    {
        "Property": "Sample.Latitude",
        "FilterValue": 2,
        "FilterOperator": 0,
        "LogicalFilterOperator": 0, // expected 1
        "Filters": null
    }
]
// This generates the filter string: (Sample.Longtitute = 1) || (Sample.Latitude = 2)

Click Simple

[
    {
        "Property": "Longtitute",
        "FilterValue": 1,
        "FilterOperator": 0,
        "LogicalFilterOperator": 0, // expected 1
        "Filters": null
    },
    {
        "Property": "Longtitute",
        "FilterValue": 2,
        "FilterOperator": 0,
        "LogicalFilterOperator": 0, // expected 1
        "Filters": null
    }
]
// This generates the filter string: Longtitute = 1 || Longtitute = 2

Expected behavior LogicalFilterOperator is set to 1 ('Or') for CompositeFilterDescriptors (Filters)

The LogicalFilterOperator that you are looking at is for the inner filters of the CompositeFilterDescriptor, the one you should look at is defined at the DataFilter level:
