Hi FeBr,
Thanks for your information.
I did the test on the same version of Office Lens as yours. As the result is different, for further troubleshooting, please confirm the following information:
1. Recent History Page--Looks nothing
like the example you gave. My Recent History Page just shows everything that was recently synced in my notebooks.
--->Please provide a screenshot of your Recent History Page to clarify this.
- What will happen after you tap the Check mark in the upper right corner? Please provide a screenshot if there is any.

- Does the issue exist after switching to a different Internet connection? No.
--->Do you mean the issue will disappear after switching to a different Internet connection? If yes, this should be caused by
network.
- I've tried the "work around" as you've suggested. Looks terrible.
--->Can you sharing more information about the result and provide a screenshot of this to help us understand it?
After saving the item, the result should be the same whether the item is imported to Office Lens or taken via the camera of Office Lens.
In addition, can you try signing out of OneDrive, OneNote, Word and PowerPoint, then signing in again to see if this will help?
Regards,
Joanne
