Last channel watched settings

Since Xfinity changed the last watched option from 10 to 5 channels (Roku), when activated, the channel selector stays on the channel currently bring watched.  It used to, automatically, (when activated) appear on the last channel watched.  As an example, when I am watching channels 809 and 810 (809 as the current channel and 810 the channel I want to swap to). The original default setting, when Last Watched was activated, the "selector" went to the previous channel being watched (810 the channel I want to switch to).  Now it remains on the channel currently bring watched (the channel I want to switch from 809). 
Is there a way to change this back?
