I am reading A Marginal Jew, have you seen this before? What is it? A Start, Keep Reading, then another Start?
It also appears that your first Start Reading asks you to pick up in the middle of a sentence. The second is a rational start at the beginning of a paragraph. I suspect that your finishing midsentence is what created this anomaly.
I've seen this quite a bit--in this case, the resource may be formatted with a logical gap--Logos reacts to it by showing where the start re-starts. You will also see this if you have multiple reading plans viewable at once which access the same parts of the same resource. My chronological bible reading plan can get pretty hard to follow sometimes in Ki / Chron because of this. Hiding the "view" of the reading plans you don't currently wants to do helps.
If I understand what you are saying, I just have one reading plan within Logos. So it can't be multiple plans.
