When typing a note, Logos sometimes replaces an apostrophe with two apostrophes; it's hard to explain; see the video in the link.
I've seen this behavior for a number of Logos versions, I'm just getting around to reporting it. I don't use any 3rd-party replacement apps. It only happens in a certain "column" range, as the video shows. I understand that columns are not a thing in Logos notes; the behavior only manifests itself within a certain distance from the left edge of the note pane is my meaning.
