I also tried looking in the COMMENTS for a lists of highlighted text to select a specific highlight and then hit delete, but could not find such a list.

Is it just the PDF document Im in, or is there something else I can try.had no trouble highlighting.

The only solution I have found is to close the document and hit Dont save.

Then I am left with the original without any highlighting.

Is that not the case If not, make sure the filter option is set to Show all comments.

Assuming you are using Adobe Acrobat Reader DC, just click on the highlight to select it and click delete on your keyboard.

Unfortunately, It does not reselect the highlighted area when I click on it, and when I reselect it by clicking and dragging, and then click delete, it does not delete it.

However, when I opened the document again just now, the highlights do show up in the comment section, and if I right click, I can delete them.

I think it may have something to do with the links in the document, and the fact that the titles (which is what I am trying to highlight selectively) may be somehow attached to the links.

At any rate, I have not had problems with other PDF documents, so I think this is an anomaly.
