Turn off community highlighting

I am a brand new Logos user--as of yesterday. I have searched the Help and the forums, but it's possible that I don't know the right lingo to find what I'm looking for, so I apologize in advance if the answer is already documented and I have just failed to find it.

When reading a book in Logos (I'm looking at Concise Theology by J.I. Packer) many passages of the text are marked with an underline and an icon that indicates that "[some number of] people highlighted this." How do I turn these indicators off? They are very distracting when I'm trying to read the book.

Thanks!
