Sqlldr log shows wrong column name when facing ORA-01722

I have a simple table with three columns.

Table name DUMMY20210527

desc DUMMY20210527

PID        NUMBER(10) 
VDATE      DATE       
SID        NUMBER(10) 

Control File

LOAD DATA CHARACTERSET JA16SJIS
APPEND INTO TABLE "DUMMY20210527" fields terminated by '\t' trailing nullcols
(
pid ,
vdate date "YYYY/MM/DD",
sid
) 

Data File

a   b   c
1   2019/01/10  X

When trying to load this file log is showing error in column vdate. however wrong value x is provided in column sid
