impdp ORA-39083 问号

impdp 从11g导入到19c，报错

ORA-39083: Object type TABLE:"user1"."TEMP_1" failed to create with error:
ORA-00957: duplicate column name
ORA-39083: Object type TABLE:"user1"."TEMP_2" failed to create with error:
ORA-00957: duplicate column name

字符集是AL32UTF8
是对汉字没处理好，所有汉字注释丢失，这两个表字段也是汉字的就显示为多个？？问号

先忽略
