Thanks for bringing this to our attention. Those aren’t documented fields for [modifiers](https://developer.squareup.com/reference/square/objects/CatalogObject#definition__property-modifier_data). Only documented fields will be available with our SDKs. Please note undocumented fields shouldn’t be relied on. 🙂
