Why is Illustrator CC adding backgrounds to my text boxes?

Question

I am working on a series of exercises from a text book that we are using in my college course. We are to create text boxes using a grid system per the instructions in the book. My problem is that all of my text boxes are appearing with backgrounds of a saturated shade of red. They do not appear that way in the book. How do I get rid of this? When I go to the Print dialogue, the preview does not show the backgrounds.

PS: The cyan and magenta blocks are supposed to be there and are meant to be spacers.

Answer 1

You've opened a file that uses fonts not installed on your system. A warning should have popped up when you opened the file. Don't ignore it, it will tell you which fonts you need. If you don't see a pop-up, you can access it under Type > Resolve Missing Fonts.
