XML deserializing not loading values to class

I have the following XML for which I auto generated a class. Once the class was generated, I had to make some adjustments to get the PayrollEmployeePayrollDate class and the PayrollEmployeePayrollCategoryWorkCode. Since I made the adjustments, both classes are loaded but all the values are null. I don't get any error unless they are being consumed during the deserialization process. Why are my values not being loaded into the class?
