C# - Generated Json fails to de-serialize "intervals" and "MonthlyStrategyList"

I have tried generating with the options (ARRAY and LIST) with the same result.

This is data from the TDA api. All previous json from their api has generated classes which then de-serialize the json.

I invoke:
var stuff = JsonConvert.DeserializeObject(json, Converter.Settings);

OptionQuoteResponse is the Generated Quicktype class from the json and is in the attached .cs file.
The json is in the attached .json file.
