A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
As far as the OneNote logic goes you are two different persons if you edit from different machines :)
I just know the exact commands in the german OneNote version (2013/2016) but just plain translating them should help you:
To hide the editor markers choose "Hide Authors" from the "History" menu.
in the same area you will find a command to mark the actual page or the whole notebook as "read" to remove the bold text from the pages which have recently changed.
Hope that helped
