private class RemoveEmptyRowCallback : IFieldMergingCallback
{
    public void FieldMerging(FieldMergingArgs args)
    {
        if (args.FieldName == "QualTitle" && string.IsNullOrEmpty((string)args.FieldValue))
        {
            args.Field.Start.GetAncestor(NodeType.Row).Remove();
        }
    }

    public void ImageFieldMerging(ImageFieldMergingArgs args)
    {
        // Do nothing.
    }
}

Code works perfectly for the QualTitle, QualSubTitle, and Qualification, it successfully removes these 3 rows
but I don’t know why is it not working for SkillsAndCompetencies, it is throwing error "Object reference not set to an instance of object, args.Field.Start.GetAncestor returned null " however the structure is the same for both.
