Issue with a conditional statement

The data comes from postgres. I'm using a JDBC input. Here is what the data looks like in the db for this particular field. I'm not manipulating this field in a filter. Is it possible to convert this field into a non-array?

DBpg=# select
DBpg-# last_assessed_for_vulnerabilities
DBpg-# from dim_asset
DBpg-# LIMIT 1;
 last_assessed_for_vulnerabilities
