Thanks for your post and welcome to the forums. It's great to see a new face getting involved in the Community.
All of our On Demand box sets are reviewed often to ensure we are making room for new content.
The Walking Dead expired so it was then removed. Series 7 is the current series where we are loading episodes on a catch up basis. As a new one is added, a previous episode is removed. Usually there is 4 weeks worth there to watch unless there was a fault with previous episodes in which case they will stay a little longer. There won't be anymore added though as the series has now finished.
The Walking Dead is certainly a popular series and I'm sure it will be back to view soon enough.
Apologies for any inconvenience.
