From another thread:
You can manually mark it as "read" by clicking on the circle and selecting "Mark Resource as Read".

• That only works if I have at least started the book in Logos. If I've read it on paper, there is no circle to click on...
• Having to first open the book and then go on to the info page before I can mark a book as read is absurd! The natural and logical place to do this is in the Library itself.
• All of these resources have been marked as 100% read, yet one has a green circle, one has a grey, and one has none at all. Yes, they do all show up green eventually, but it takes 20 minutes or more. (I'm still waiting for one I marked an hour ago...)
