Export/Import/SQL Loader :: Field In Data File Exceeds Maximum Length?

I am struggling with a simple data load using sqlldr

Ref: I am running Oracle 11.2 on Linux 5.7.
===========================
Here is my table:
SQL> desc ntwkrep.CARD
Name                                                              Null?    Type

[code]...

Looking at the actual data and counting the characters for the "REALIZES" column data, I see that it is roughly slightly over 1000 characters.

So, attempting various ideas to fix the problem, I tried changing nls_length_semantics to "char" and recreating the table, but this still didn't work and still got the same data load errors on the same rows.

Then, I changed nls_length_semantics back to byte and recreated the table again.This time, I altered the table manually as:
SQL> ALTER TABLE ntwkrep.CARD MODIFY (REALIZES VARCHAR2(4000 char));

Table altered.

SQL> desc ntwkrep.card
Name                                                              Null?    Type
----------------------------------------------------------------- -------- --------------------------------------------
CIM_DESCRIPTION                                                            VARCHAR2(255)
CIM_NAME                                                          NOT NULL VARCHAR2(255)
COMPOSEDOF                                                                 VARCHAR2(4000)

[code]...

Here is a copy of the first row of data which fails to load every time no matter how I change the "REALIZES" column in the table.
