Images have self-generated pop-ups when converted to PDF
I have created a PDF (from MS Word) which contains text and images. The images were taken on my smartphone and inserted into Word. There are no tags or properties that have any 'layman's' description of the content of the images (either when standalone images or after insertion into Word), but once I have saved the Word document as a PDF and open it in Acrobat, if I hover over the images a pop-up shows with a brief generic description (it has detected some trees, so has added "A close-up of a tree - Description automatically generated") - I can't see where this is happening or how to stop it. Any help appreciated.
