Single-End Analog Input

I am trying to read a voltage using an analog input on a NI USB-6008. I have tried using a Differential and it worked, however, I am constrained and would prefer to use Single-End to read the voltage. However, when I create an instance of an AnalogSingleChannelReader with a Terminal Coniguration of any type other than Differential, it still operates like a Differential. Any ideas as to why this isn't working? And yes, I do know that the Terminal Configuration currently is configured for a Differential in the code.

public class AnalogInput
    {
        #region Import Dlls
        [DllImport("NationalInstruments.Common.dll")]
        static extern void Import1();
        [DllImport("NationalInstruments.Common.Native.dll")]

        static extern void Import3();
