我的获取标签和可选值接口返回：

{"errcode":0,"options":[{"tag_values":[],"tag_name":""},{"tag_values":[],"tag_name":""},{"tag_values":[],"tag_name":""},{"tag_values":["南宁1","南宁2","南宁3","南宁4","南宁5","南宁6","南宁7","南宁8","南宁9","南宁10","玉林","柳州","贵港","百色","桂林","北海","崇左","钦州","河池","来宾","梧州","贺州"],"tag_name":"群发组"}],"errmsg":"ok"}

但是当我在调用为客户设置标签接口时，返回如下错误里信息，是为什么？？？？

{"errcode":0,"errmsg":"ok","buyer_resp":[{"errcode":9300807,"openid":"oyheus-xxx","errmsg":"标签值无效，不是可选标签值"},{"errcode":9300807,"openid":"oyheusxxx","errmsg":"标签值无效，不是可选标签值"}]}
