Inappropriate indication for pdf

I have done OCR many time but only this particular document appears as a pdf document, not pdf+text

created using adobe acrobat pro and DEVONthink.

this is file info opened with Preview.app.

Does restarting the app fix this? And which version do you use? The current versions are 3.9.15 and 4.1

I am using DT4.1 now. same happens for same item after restarting the app. (just one item in my case:)

Is there any more information to investigate this problem? please understand that I may be slow to respond. thank you.

Does reimporting the document make a difference?

I found zero difference here.

Could you share this document via PM so that we could check this? Thanks in advance!

Is anything reported in Window > Log?

nothing reported. but after uploading and downloading via drive.google.com, the problem has been solved… I will try one more OCR feature.

It’s not an unauthorized reproduction for software support purposes. We aren’t asking for a copy for leisure reading but for the purposes of investigation. That being said, you are under no compulsion to provide the file but it’s something to be aware of.
