While using a custom seedlist and using HASHLOV on a column different from the column being applied, the value always results in null no matter what the input is.
Reviewing the TDM documentation and analyzing the results from your imported custom seedlist, we noticed is the first names are all showing as NULL. This is because the CSV file structure is off, and FDM is picking up the "name-value" pair as firstname,NULL. Causing the masking to always return the value NULL.

Looking at the first record in your CSV (Line 2) we see:
CUSTOM_PERSON_NAMES,Dante,NULL,Brown,Smith,"Smith, Dante Brown",Dante B Smith,Dante B. Smith,Dante Brown Smith,Dante Smith,[email protected],71186
Where CUSTOM_PERSON_NAMES is the Category Name and all remaining comma-separated fields are considered name-value pairs. Resulting in the following
|Dante B Smith||Dante B. Smith|
|Dante Brown Smith||Dante Smith|
Release : 4.10
Component : Fast Data Masker
You need to strip the header row from the CSV, restructure the file into Name/Value pairs, and reimport the corrected seedlist into the scramble database. Then rerun the masking job.
