Trouble with XML Deserialization into XSD generated classes

I have a rather detailed xml file. Below is the top level nodes (I have included the ellipse as the lower level nodes are all well formed and properly filled with data):

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <Models>...</Models>
    <Data>...</Data>
</config>

I have created an xsd file from using the Visual Studio 2008 command prompt:

xsd sample.xml

This generates the xsd file just fine. I then auto generate classes from the xsd with the command:

xsd sample.xsd /classes

For the deserialization of the xml file into a class object, I'm using the read function in the helper class:

public class XmlSerializerHelper<T>
{
    public Type _type;

    public XmlSerializerHelper()
    {
        _type = typeof(T);
    }

    public void Save(string path, object obj)
    {
        using (TextWriter textWriter = new StreamWriter(path))
        {
            XmlSerializer serializer = new XmlSerializer(_type);
            serializer.Serialize(textWriter, obj);
        }
    }

    public T Read(string path)
    {
        T result;
        using (TextReader textReader = new StreamReader(path))
        {
            XmlSerializer deserializer = new XmlSerializer(_type);
            result = (T)deserializer.Deserialize(textReader);
        }
        return result;
    }
}

When attempting the deserialization with:

var helper = new XmlSerializerHelper<configModels>();
var obj = new configModels();
obj = helper.Read(filepath);

I receive an error that I have deduced is because the deserializer is looking for the 'Models' node but the corresponding class name was generated as a combination of the root node and the 'Model' node (configModels). Why are the class names generated like this?

I tried to deserialize from the top node using:
