我正在使用 reledmac 准备一系列文本的版本。在描述环境中，每篇文本都从新的一页开始，前面有两行信息（手稿书架号和对开本）。我需要每篇文本的两行和标题都出现在页面上的同一位置。大多数情况下，它运行良好，但在某些情况下，reledmac 似乎无法在方便的位置计算分页符，并“拉伸”页面顶部两行描述之间的空间。
在下面的例子中，两行描述（MS1 和 MS2）之间以及描述和文本开头之间的空白在第一行文本（Sermo secundus）中被过度拉伸，在第二行文本（Sermo tertius）中则正常。我的例子有点长，对此表示抱歉，但我不能使用 lipsum，因为我需要在给定的布局中显示带有造成问题的关键脚注的实际文本。

第一篇文字：
第二段文字：
我如何确保两行描述和布道的开头始终位于页面上的同一位置（垂直方向），并防止空白处被拉伸？我尝试在布道文本中使用\ledpb和\lednopb，但无济于事。或者，我尝试在顶部的两行中使用表格，而不是描述环境。我设法防止了两行之间的拉伸，但随后这两行之间的空间和布道的开头被拉伸了，这只会使问题转移。
