When using the highlighting tool (turning is on in the toolbar at the top), when you depress the mouse button and swipe to highlight text, the text from the page before 'bleeds' through so you can't see what you're highlighting.
Photos: 1 - is the page where I want to highlight 2 - is highlighting in progress (note text is blanked out and '11. RFP 23-P23....' is showing up. 3- is the page before, page 5, with that text on it.
