It's basically double the amount of work that he used to have. But that's not all because he gets complaints
23
24
00:01:40,110 --> 00:01:46,250
from users saying that "hey in your app some of the layouts look really weird".
24
25
00:01:46,260 --> 00:01:47,670
"It doesn't look right."

所以我想删除它怎么办？
注意：：我有一点编程经验
解决方法
将“RemoveDoubleNumbering.exe”放在字幕所在的文件夹中并打开它。将处理此文件夹及其所有子文件夹中的字幕。还将创建备份。
需要 .Net Framework 4.5+。
如果有人担心病毒，请自行编译：
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;

RestoreSubtitlesFromBackup(GetCurrentDirectory());
Console.WriteLine("Backups restored.");
return;
}
var subtitlesDirectory = GetSubtitlesDirectory(args);
var subtitleFiles = GetSubtitleFiles(subtitlesDirectory);
RemoveDoubleNumbering(subtitleFiles);
