On_by_default field in field missing in .net SDK

Using the .NET SDK, we are trying to download the catalog. When working with modifiers, there is a field "on_by_default field " that is available in the API, but it doesn’t seem to show up in the SDK. Where can I get this value using the SDK?

thank you

Checking in with the Catalog team on this one, and you’re right it’s missing from both the SDK and the docs. However, they’ve informed me that if the selection_type is set to SINGLE, then the MODIFIER with the lowest ordinal will actually be the one that is on_by_default == true. Thus this field is actually redundant and you should be able to figure it out without it for now.
