How to disable the progress bar at the top of each slide

I have just published a course and upon review, there's a progress bar at the top of every slide except the very first title slide. I didn't put it there, (it's not a slider) and have no idea how to get rid of it, but I have to because it's blocking content. (Screenshot attached.)

To add insult to injury, the progress bar doesn't even work! It stays at 0% all the way through!  How can I get rid of this?
