两个几乎相同的 bibtex 条目，一个引用另一个而不引用（Overleaf 用户）

Question

更有趣的是，在我为 SE 制作的 MWE 中，它们都引用了。我无法重现 MWE 中的错误，在文档中只有当我开始输入时WorldBank2017，whileWorldBank2012被建议为键\citep{，但如果我完成引用并编译，它只会给出问号和相应的错误

Package natbib Warning: Citation `WorldBank2012' on page 6 undefined on input line 125

你知道为什么会这样吗？

不是 MWE

更新

它似乎确实引用了该条目，只是输入了一个问号，而不是作者-年份格式。事实上，参考条目也缺少作者姓名。
