Lyx2.1-由于某种原因出现新的空浮点定义（无法再编译）

我曾使用 LyX 撰写论文，大部分情况下，它都运行良好。然而，当前的编译错误让我感到困惑。添加几个浮点数后，我现在收到以下错误：

neither of these is meaningful inside \write. So
I'm forgetting what you said and using zero instead.

我首先尝试删除新的浮点数，但这并没有什么不同。然后我尝试编译一个较旧的提交，结果很好。tex然而，当我比较两个版本的导出时，我发现一个空的浮点构造已附加到用户定义的浮点定义中：

\floatstyle{}
\newfloat{}{}{}
\providecommand{\name}{}
\floatname{}{\protect\name}

如果我没有尝试定义新的浮点数，为什么会发生这种情况？我该如何阻止它发生？

编辑：如果我删除新的浮点定义，我可以进行tex导出编译，但是布局在某些地方很混乱，并且我的所有引用都被破坏了。

更新： 根据评论，以下是文档的前言tex。首先是旧文档（编译得很好）：

答案1

我相信我找到了问题所在。虽然我不清楚为什么会发生这种情况，但似乎我的一些浮点数一下子就坏了。我将它们引用为“float: Model”（自定义模块），在某个时候，它们都被重新指定为空白的浮点选项。取而代之的是“float: model”，但如果您单击浮点标签（每个浮点左上角的选项卡）来更改浮点类型，它不会被选为任何可用选项。这一定是在前面的内容中创建了那个空的浮点定义。

答案2

我遇到了同样的问题。浮点数是s，我在表中Table插入了一些代码s。突然，浮点数的类型显示为，但浮点数的实际类型（如设置中所示）变为空。然后我无法编译文档。Listinglisting

为了解决这个问题，我进入了浮动设置并将浮动类型设置为Table。我插入代码清单的所有浮动都需要这样做。

我相信这是 LyX 的一个错误：当将 acode listing插入表格单元格时，并且当表格是浮点数的一部分时，整个浮点数的类型将被清除并变为无效。
