I made changes to properties, but they aren’t showing up in the export

It could be you haven’t “committed” the old export and “published” the new one. Here are the steps:

1. File > Export…

2. Select the desired Export Definition

3. Commit or Rollback. Commit if the receivers accepted the file. Rollback if they rejected it.

4. Publish (prepares for an export)

5. Export Full or Changes
