Today I was looking at my watching list and noticed that a lot of old dramas appeared there. Most of them I remember marking as completed, and some are still showing my rating even though they’re listed as ‘watching’. Many others have lost their ratings. These dramas were ones I watched while they were airing. 


For example: W is on my watching list showing a 10/10 rating, and I do remember that I loved W and completed it in 2016 when it aired.

You can check the history log, the last update was in 2016, so it’s not possible for it to undo or mark itself as watching.
