Encoding Problem using the Highlight Tool?

CVLogan

I've manually added a PDF into the desktop app (Windows) and had no trouble using the highlight tool for the first few introduction pages of the document (either using the tool at the top of the page or just selecting the text and clicking highlight).

Now that I'm working in a different section, when text appears in the annotation panel it recognizes the correct number of characters and spaces but not the same characters as in the document. When I try to annotate a different part of the body of text it seems to have the same problem regardless of location. Really only the introduction section seems to correctly identify the annotated text.

I've reuploaded the document and just updated the app and the same problem keeps happening: the annotation works as it should for first few pages then it seems to have a problem with encoding using both the highlight and the underline tool for the rest of the body.

I'm not very proficient with Zotero yet so if there's a simple solution that I'm missing I'd be very grateful if someone would please enlighten me. I've attached an example here :

This is most likely a PDF file issue. You can check if other PDF viewers have the same problem.

I think the only option is to recreate the text layer by running it through OCR software.
