Hi Dave,
You may have answered your own question. These are custom QuickBooks fields you have created in QuickBooks not Method. Therefore Method must follow the same properties as QuickBooks for these fields. Your alternative is to create custom fields in Method which as you know can have different properties.
Hope this helps,
Val
