datawindow character length using ASA 16

PB 12.5.1 Build 4015, Win7 professional

When I create a dw using an ASA 12 db (or lower version), the character column lengths in the datawindow match the character length in the database. 

If I create the exact same datawindow using an ASA 16 database, the character columns in the datawindow are 3 times the size of the character lengths in the database.

Suggestions.
