Thank you very much for the question and I am very sorry about the issue!
With options to export drawings in Model Space linked to Paper Space layouts, the autotexts can't be exported correctly. The reason for it is because the autotexts cannot be evaluated with the translator options "PaperSpace with ... Views Content", as they just show the referred views content in PaperSpace, meaning #LayId for example.
In order to achieve the same look as PDF export, we need to use Paper Space with Drawings as Blocks or Model Space instead, the DWG will show the correct content, but less "smart" of a DWG file, more like a plot or PDF.
I hope this explains the situation. I am very sorry for the inconvenience! Please let us know if you have any questions regarding this topic.
Thank you very much!
