[VB.NET 2010] List Population from a DataSet/DataTable

I had this program working a while ago and I came back to it and am having some issues. I am able to Populate a List from a DataSet well enough but for some reason my initial List persists through all other lists that I try to populate after that. That is to say that the DataSet for the first Parts group is copied over into all other datasets throughout the application.

Code:

Private Sub RetrieveProtectionFromDB()
        Try
            Using udtconn As New SqlConnection(sBoMConnectionString)

                udtconn.Open()
                Dim daProtection As New SqlDataAdapter(New SqlCommand("SELECT * FROM Part, Part_Type, Part_Subtype, Part_Type_Subtype_Xref, Part_Details_Motor WHERE Part.Part_Type_Xref_Id = Part_Type_Subtype_Xref.Part_Type_Xref_Id AND Part_Type_Subtype_Xref.Part_Type_Id = Part_Type.Part_Type_Id AND Part_Type_Subtype_Xref.Part_Subtype_Id = Part_Subtype.Part_Subtype_Id AND Part.Master_Part_Id = Part_Details_Motor.Master_Part_Id And Part_Type.Part_Type_Name = 'Motor Protection'", udtconn))
                udtconn.Close()

                daProtection.Fill(ds)
                daProtection.Fill(dt)

                'Creates new motor class with the information that was pulled from the database
                Dim newProtection As New clsMotorProtection()
                newProtection.ProtectionHorsepower = CType(dt.Rows(0).Item("Horsepower"), Decimal)
                newProtection.ProtectionPartType = CType(dt.Rows(0).Item("Part_Type_Name"), String)

I put two DataSets on here so you can compare.
Also, i apologize for the length of the code. I know it could be more concise but this is a pickup project.

Thanks for any insight you may offer,

Can't really say without seeing the DATA. Probably would help you as well.

DEBUG.PRINT out the statements (VB6, sorry). Probably not what you expect
