API List field not showing

Hi - when connecting to a valid API with known good JSON, after confirming the config and ensuring the schema is correct, I still can’t see the “List Field” drop down when adding to the List. Seems to be a bug given the instructions shown here: API | Momen Docs

Could you send an example JSON?
At the moment we have an issue dealing with array of arrays in APIs. This is being fixed this year.
