Problems Highlighting in Document Mode

Problems highlighting in document mode.
I was highlighting as I needed (specific parts of sentences/paragraphs) and when I get to one page I am unable. It only allows highlighting everything in a block not specific portions I need. If I go to the next page it goes back to normal behavior. I can’t afford to miss pages.

Hello

Kind Regards,
