### Description

I tried downloading a SpongeBob episode with captions, but the second episode doesn't work.

I downloaded this episode: https://www.nick.com/episodes/tn6nft/spongebob-squarepants-say-awww-patrick-the-mailman-season-13-ep-9

I ended up with four files:
> SpongeBob SquarePants - 'Say ‘Awww!’_Patrick the Mailman' S1 [a9840a69-b661-4875-9a47-b1aea041b6a2].en.vtt
> SpongeBob SquarePants - 'Say ‘Awww!’_Patrick the Mailman' S2 [d7b4d532-21e3-405e-a72d-f537eee01438].en.scc
> SpongeBob SquarePants - 'Say ‘Awww!’_Patrick the Mailman' S3 [9bdd615b-f5ff-422c-92ac-6743b6efeac7].en.vtt
> SpongeBob SquarePants - 'Say ‘Awww!’_Patrick the Mailman' S4 [d059ade0-5abc-4be5-99ad-27ec8f9adced].en.vtt

S1 is the captions for the theme song, S3 is the first episode in the pair (Patrick the Mailman) and works fine, S4 is for the second episode (Say Awww!), but only has one empty line in it.
