As of 4.5c Beta 2 (4.53.0.2084) at least i have noticed that reading plans are not behaving well.
On the home page if I am behind I can right click the day and select "Adjust plan from today" This works and resets the readings based upon today's date.

On the other hand, if I am in the mode to view the reading list, if I right click I get slightly different phrasing (a clue to the problem?) and "Adjust plan from here" does nothing at all when I click it.
