Alright, maybe my code was too restrictive on that part, because there is duplicate subtitles. What you can do is to remove either the .srt or the .txt version (it should be the same to be honest). It shouldn't be an error though, as I should've added an additional case.

I used files from https://github.com/Koko-boya/Grasscutter_Resources/tree/3.0/Resources/Subtitle/CHS

[ToaHartor]

Hmm, maybe since 3.0, the files no longer have the txt extension but have the srt one instead (which is their right format). I'll make a fix to choose the srt extension in priority, but as a temporary fix you can remove the txt ones I believe.

[CarterLi]

It worked with .txt files removed
