使用initialValue分配初始值后，删除动态添加的控件将删除多个控件

Question

复制步骤 在编辑器的第67行，getFieldDecorator（“ keys”，{initialValue：[]}）;，给initialValue初始值为1或任何值。

期望什么？ 预期结果是：分配后默认情况下添加了一个控件，并且删除添加的控件的控件的k值不相同。

实际上发生了什么？ 如果您将值指定为1，则在添加3个控件后，删除数组索引为1的控件。您会发现这两个控件被同时删除，或者第一个控件具有删除按钮，但无法删除。第二个控件没有删除按钮

sendbox editor进行测试

我该怎么做？
