JabRef 评论 @PREAMBLE 条目

Question

当我打开.bib包含条目的文件时@PREAMBLE，JabRef 在保存后会注释此条目并拒绝下次打开该文件。我该如何防止这种情况发生？

.bib使用 JabRef 之前的文件：

@PREAMBLE{{\providecommand{\noopsort}[1]{}}}

@Article{AF,
  author =        {M. Anderson and T. Feil},
  title =         {{Turning Lights Out with Linear Algebra}},
  journal =       {Mathematics Magazine},
  year =          {1998},
  volume =        {71},
  number =        {4},
  pages =         {300 -- 303},
}

.bib在 JabRef 中打开后的文件：

% Encoding: UTF-8@PREAMBLE{{\providecommand{\noopsort}[1]{}}}

@Article{AF,
  author =        {M. Anderson and T. Feil},
  title =         {{Turning Lights Out with Linear Algebra}},
  journal =       {Mathematics Magazine},
  year =          {1998},
  volume =        {71},
  number =        {4},
  pages =         {300 -- 303},
}
