Thank you very much for sharing the report and I am very sorry for the issue!
From my experience, this is not the expected behavior. What you see on the layout should be exported correctly into DWG, at least for the linework and information. Before diving deeper into the detail, I would like to make sure that the latest update is installed for your current Archicad. Also, please make sure to update all drawings before publishing to DWG.
If this does not help, I would like to kindly ask for the file having this issue, along with the translator used for publishing purpose. Please let me know if you need a secure place to upload them!
Looking forward to hearing from you!
