Crystal Reports 2016 with ODBC

I have been developing reports for use with a PostgreSQL database using ODBC for the last 2 years. I just upgraded to Crystal Reports 2016 from Crystal Reports 2013 and found that all of my reports now treat Boolean fields as Boolean even though my ODBC driver has a checkmark in "Bools as Char".

This has broken every report written in the last two years.

Is this a known issue or am I misunderstanding something?

Thanks.....Peter
