Episode List

There is an issue with the below title: 

Na Aana Iss Des Laado - Episodes - IMDb

There are two episode lists namely '2009' and 'Unknown' as seen on the title page

2009 list has just one entry of Ep.1

Unknown list has entries from episodes 2 to 870

While adding Director credits, the episode list pop up window doesn't show the 'unknown' list

The list that shows up has some episodes missing; for example I need to add the below episodes to add Director credits; but there are missing episodes as marked:

1.497

I need help to correct the episode list name from 'unknown' to 2009 / and delete the episode list titled '2009'

Then I need to add episode 1 to the (now) episode list titled '2009'

OR

How do I add/locate the missing episodes from the episode list that is currently visible.
