We have not faced a different behaviour between in session or saved DWG settings using Revit 2022.

Please try the following:

1 - In the Revit native printer settings, remove/delte the selected Print range, so that is says in-session. Click the Close button after that. 

2 - Ensure that you select a folder destination inside Docuflow that actually exists. 

3 - Export the DWGs using Docuflow.

We are looking to the DWG scenario that you described and will come to a conclusion soon.

The export of the drawing list requires the application Reports sold separately. When Reports is installed then it is possible to export the drawing list.

addition to previous post:
we use revit 2022

Good day
we use Docuflow 6.18.0.0
PDF creation works flawlessly, dwg's are only created with the export setup "in session". The company's own export configuration works perfectly from the native Revit dialog, but not at all from Docuflow. No files are generated.
Also the Drawing List function does not work. I set the check mark in the main menu at "Documents / Drawing List" but still can't select a list in the ribbon "Documents" in the pull-down "Revit Schedule...", because the pull-down menu is grayed out.

thanx in advance,
