❔ Bug in blazor?
because the data is correctly generated, thats why the tables are filled up, its the "totalrow" that gets the values from the specified columns, this is just calculated. 
TotalRow:
public void Correct()
    {
        foreach (var index in OfColumns)
        {
            ColumnValues[index] = 0;
            ColumnValues[index] = ParentComponent?
                .Rows
                .Sum(r => ((r as Row)?.Cells[index] as DecimalCell)?.Value ?? 0) 
                                  ?? 0;
        }
    }
TotalRow:
public void Correct()
    {
        foreach (var index in OfColumns)
        {
            ColumnValues[index] = 0;
            ColumnValues[index] = ParentComponent?
                .Rows
                .Sum(r => ((r as Row)?.Cells[index] as DecimalCell)?.Value ?? 0) 
                                  ?? 0;
        }
    }
ParentComponent Table:
public void OnChildrenRendered()
    {
        foreach (var baseRow in Rows.FindAll(r => r is Row))
        {
            var row = (Row)baseRow;
            if (RenderedRows.Contains(row)) continue;
            Rows.Remove(row);
        }
        RenderedRows.Clear();
        CorrectTotalRow();
        StateHasChanged();
    }
    
    public void CorrectTotalRow()
    {
        ((TotalRow?)Rows.Find(r => r is TotalRow))?.Correct();
    }

The total row shows and calculates the sums of columns 2, 3 and 4. As you can see it works perfectly for the second table but not the first table, and here comes the strangest thing, when i leave out the @if (CategoryLines is not null) check, and thus not show a spinner, it does show the totals for that table! Which is super strange because the second table does not require that! Anyone an idea why this might be?

Both tables use the exact same component and child components 
<Table Names="@(new[] { "Groep", "Totaal ex.", "Totaal btw", "Totaal incl." })" 
               MaxRows="@(CategoryLines?.Count ?? 0)">

               {
                   var category = CategoryLines[i];
                   var index = i;
