flink 1.17.2,doris-3.1.0主键模型灵活列更新导入失败

1.doris已设置
"enable_unique_key_merge_on_write" = "true",
"enable_unique_key_skip_bitmap_column" = "true",
2.flink已配置
sink.properties.unique_key_update_mode' = 'UPDATE_FLEXIBLE_COLUMNS
但是执行flink执行任务报错
Caused by: org.apache.doris.flink.exception.DorisBatchLoadException: org.apache.doris.flink.exception.DorisBatchLoadException: stream load error: stream load error: [INVALID_ARGUMENT]Don't support flexible partial update when 'columns' is specified, see more in null
