### 🚑 其他信息
1. 非嵌套结构一切正常
2. initialValue中 没有嵌套的空数组也正常
3. 使用Antd Form还原相同场景无法重现 (附Antd Form的代码 https://codesandbox.io/s/fu-za-de-dong-tai-zeng-jian-biao-dan-xiang-antd-5-3-2-forked-vc7et4?file=/demo.tsx)

Start with the linked CodeSandbox App.tsx and reproduce the nested ProFormList case using initialValues and preserve=false. Compare it with the linked Ant Design Form example to isolate the ProFormList behavior; done means deleting the final nested item leaves no empty object and removes all data.
