Use Fast Schema Change (-populate) to turn off fast schema change when you are adding fields to a table. Fast schema change is the default behavior.

In earlier versions of Progress, adding a field to an existing database table is a time-consuming process for large databases. The DBMS updated the data in each row of the table to reflect the newly added field. Now Progress provides a fast schema change when you are adding fields to a table when all qualifying conditions are met. If all conditions are not met, adding a field causes Progress to update every row in the table.
