redux-form initialValues being created as a Map

I've got a redux-form and I'm trying to initialize the form using initialValues. Given the following code, the form isn't being populated with either the name or the age:

const EmployeesForm = reduxForm({
  form: 'addEmployee',
  enableReinitialize: true
})(EmployeesFormComponent)

export default connect((state, ownProps) => {
  const initialValues = { name: 'Jason', age: 24 }
  return {
    initialValues: initialValues
  }
})(EmployeesForm)

But in the web dev console when inspecting the next state on redux, I can see that form.values and form.initial are both Map objects that hold those initialValue values.

How should I be transforming the object so that it "fits" into the form. BTW I'm using: import { Field, reduxForm } from 'redux-form/immutable' and it's redux-form 6.8.0.
