biblatex 中“哈佛风格”作者年份引用存在问题

Question

因此，对于我的学士论文，我想使用“哈佛”引用样式，如果引用的论文有 2 位作者，则输入“authorX 和 authorY（年份）”，如果论文有 3 位或更多作者，则输入“authorX 等（年份）”。这在大多数情况下都行得通，但我有几个来源不起作用。问题一是，在某些引文中，它会打印“authorX、authorY、authorZ、等（年份）”。问题二是，在少数情况下，它还会打印作者的名字或姓名首字母，而我只想在所有引文中显示姓氏。我像这样导入了 biblatex \usepackage[backend=biber, citestyle=authoryear-comp, bibstyle=numeric, maxcitenames=2]{biblatex}。
