Opt number is appearing in my exported CSV

In my exported CSV, the opt number for every checkbox selection is being included. Is there a way to hide this opt number? I read in another post that this was supposedly fixed several updates ago, but I’m running Version 1.6.1 and still getting the {opt#…} in my exported spreadsheet.

Examples:
Other, {“opt1779309″:”Other”}
Staff Person, Other, {“opt5991436″:”Staff Person”,”opt6536169″:”Other”}

Any help would be greatly appreciated. Thank you.
