If getting behind in the biblereadingplan in homepage and then mark 4-5 passages as done the date will disapear.
Normaly(?) first day in list displays with date in the plan but the rest of the days just displays with "name" eg. Monday. You can mark one or two days as read in the list and the date is still there.
When marking 4-5 days as read then the date disapears and it's impossible to know how far behind you are in your reading.
This is not new behaviour in Beta 6
