Can't get enumeration list selected value

Hello, I have an rtc custom work item with the field 'Design Authority" which is a check box of 5 options.


I checked my rtc settings, and i believe it is an enumeration list


But If i try to query for `rtc_cm:DesignAuthority` my rtc_client returns a list of values, with no way to determine which value was selected


I'm curious, is there a different way I can retrieve the selected value of this enumeration list? I checked the raw_data variable as well, and found out that it includes a URL which shows all the xml enumeration options, but still no way to determine which value the user has selected inside the work item
