Empty idd suffix

Dear RESTCountries development team, I am writing this email to report a possible data inconsistency in a response of the “list of codes” API operation (https://restcountries.com/#endpoints-list-of-codes).

When searching for Canada (e.g., with the API request: https://restcountries.com/v3.1/alpha?codes=CA), the response property idd.suffixes (an array of strings) contains a single element whose value is an empty string. Is this a data inconsistency? Please, find the response attached here:api_response.txt

Best regards, Juan Carlos Alonso Valenzuela
