我目前正在撰写论文，并使用德国班贝格大学的模板（https://github.com/UBA-PSI/psi-thesis-guide）。当我在 documentclass 中添加 oneside 命令并加载它时，我的 \cleardubblepage 和标题消失了。你知道为什么吗？
这个模板中有很多命令，所以说实话我甚至不确定在这里要添加什么命令。
\documentclass[
12pt, % The default document font size is 11 (recommended), options: 10pt, 11pt, 12pt
oneside, % Two-side layout is recommended; uncomment to switch to one-sided
ngerman, % replace with ngerman for German; not fully supported so far -- requires changes elsewhere
onehalfspacing, % Single line spacing (recommended), alternatives: onehalfspacing or doublespacing
%draft, % Uncomment to enable draft mode (no pictures, no links, overfull hboxes indicated)
nolistspacing, % If the document is onehalfspacing or doublespacing, uncomment this to set spacing in lists to single
%liststotoc, % Uncomment to add list of figures/tables/etc to table of contents (not recommended)
%toctotoc, % Uncomment to add the main table of contents to the table of contents (not recommended)
parskip, % add space between paragraphs (recommended)
nohyperref, % do not load the hyperref package (is loaded in setup.tex)
%headsepline, % print a horizontal line under the page header
consistentlayout, % layout of declaration, abstract and acknowledgements pages matches the default layout
%final, % Uncomment to hide all todo notes
]{PSIThesis} % The class file specifying the document structure
我非常感谢任何帮助，如果你们中的一些人知道可能知道什么样的其他命令可能会有问题，我会将它们添加到这个帖子中。
很抱歉，我不知道应该在这里添加哪些命令......
PS. 偶数页和奇数页的页眉消失了。
这些是我的页眉和页脚命令。
