Steps to reproduce:

1. Go to Publishing > Staging
2. Enable staging without any changes (DDL is not staged)
3. Go to Control Panel > Content > Dynamic Data List
4. Create a Dynamic Data List
5. Add a Dynamic Data Definiton to the List, choose any field (eg. Color)
6. Select the newly created Data Definition
7. Click on the 3 dot at the top right corner > Export
8. Export the Dynamic Data list and download the created file

Expected result: In Dynamic_Data_Lists-202005081442.portlet.lar in the group folder, both 20127\com.liferay.dynamic.data.lists.model.DDLRecordSet\ and
37956\com.liferay.dynamic.data.mapping.model.DDMStructure\ are present. Dynamic Data Definitions should be available in separate folders in JSON file

Actual result: In Dynamic_Data_Lists-202005081442.portlet.lar in the group folder, only 20127\com.liferay.dynamic.data.lists.model.DDLRecordSet\ is available

Please note that the timestamp on the .lar file and the group ID folders are arbitrary.
