Using TypeMock With CSLA Broken In New Versions

public class Fee : BusinessBase<AccountFee>
{
    private static readonly PropertyInfo<FeeCalculationType?> _CalculationTypeProperty = RegisterProperty<FeeCalculationType?>(p => p.CalculationType);

    public FeeCalculationType? CalculationType
    {
        get { return GetProperty(_CalculationTypeProperty); }
        set { SetProperty(_CalculationTypeProperty, value); }
    }
}

When RegisterProperty is called the property information is added to a singleton collection and an exception is thrown if a duplicate one is added for the same object type. 

The newer versions of TypeMock seem to be re-initializing the static readonly members of the classes.  Is there a way to disable this functionality so that it works like the older version or is there a certain way that our tests need to be written to work properly with the new versions?  We do have code that uses a Mock data layer and doesn't use TypeMock and those tests work fine unless the TypeMock tests are executed first in which case then they break usually due to the PropertyInfo values being null.
