Twitch VODs aren't displaying in Auto Contribute panel correctly

Description

If you visit a Twitch VOD, it is not being displayed in the Auto Contribute panel correctly. Each VOD is listed individually instead of under one creator.

Steps to Reproduce

1. Enable rewards if not already enabled.
2. Navigate to twitch user video page (I used https://www.twitch.tv/adam13531/videos/all)
3. Play a video
4. Wait a bit of time, go back to Rewards page
5. VOD is listed.
6. Go back to video
7. Click on another VOD by same creator.
8. Wait a bit of time, go back to Rewards page

Actual result:

VODs are listed individually instead of grouped under one creator as they were on b-l:

Expected result:

VODs for same creator should be listed once. So in the above example they should be grouped under something like adam13531 on Twitch

@srirambv I don’t think it’s related to non-english characters being in the name… I can reproduce this with a brand new profile using the following VOD:

• https://www.twitch.tv/videos/319210868

The title of the video is Let us GAME and the users name is Ninja which are all english characters. However, playing the above video still displays the following:
