Trad Chinese- Struggling to import Youtube videos

I am trying to import this youtube video into Trad Chinese at LingQ:

【博恩夜夜秀】第一季有很多問題?foodpanda都幫你解決! - YouTube

When I try it comes up with the following error message: " Error:detail: Subtitles can’t be used "

The video does have traditional Chinese subtitles so I am unsure why I get this error. Can anyone help?
