Sorry for the delay in response.
As I understand, you are copying and pasting text from the doument in the Adobe Scan to other location. Is that right?
If yes, did you check if the issue occurs with a paticular file?
I have checked the screenshot that you have shared. Could you please let us know the applicaiton where you are trying to paste the text.
It would be helpful if you can share the file on which the issue occurs. We would like to check it on our end.
To share file, you can use the steps provided here https://forums.adobe.com/docs/DOC-7161
Let us know if you need any help.
