Why text highlighting with Okular 1.3.3 doesn't work with one pdf?

I should annotate a manuscript, i.e. highlight text and add comments. According to the publisher, the pdf file can be annotated, so it should contain text. I have tried to use Okular 1.3.3 (in Kubuntu 18.04) but with no success. The text highlight cannot select text but highlights large arbitrary shaped areas. However, with some other pdfs (generated from latex files) the highlighting works, including mathematical expressions. Could the reason be that in this manuscript pdf the commenting is not allowed, according to Adobe reader 9? Do you now any solution how to do highlighting? How to trace what is wrong with the pdf?
Extra note: pdftotext can produce text, so there really seems to be text, but the text selection or highlighting in okular doesn't work.

Some PDF files contain text; others are basically just images of text. If the file you're working with doesn't actually contain the underlying text, but only pages full of pixels, then you won't be able to do text-oriented things to it.
