使用 TitleGM 时 vbox 溢出，导致标题页前面出现空白页

Question

我在标题页之前看到了一个空白页，我怀疑这是由于我收到了 vbox 溢出警告。问题是我不知道如何正确调整 vbox 设置！有人能帮忙吗？这里有一个显示问题的示例文档：

Answer 1

罪魁祸首是\vspace{0.5\textheight}和\linespread{1.2}。我缩短了所用的长度\vspace，并\linespread在构建标题后将行移到了某个位置。我还删除了一些虚假的空格（通过%在适当的位置插入（我希望我已经删除了所有空格）），并将“John Svazic”更改为罗马字体（拉丁现代字体在无衬线系列中不提供小写字母）：
