API Creating cash account does not work?

Using the Navexa v1 api endpoint to create a cash account. (/v1/cashAccount post) Appears to succeed. it returns an integer response (undocumented in the API docs), but will assume is the Id of the newly created cash account. But then Querying the account list, does not return the new Cash Account? If i repeat the POST again, it will return the same ID, but checking created accounts does not show the new account. Confirmed by logging into website as well. Please advise if I am doing something incorrect.
