Strange behaviour when using removeValue mode="array"

[nbentoneves]

I'm having an issue with the removeValue function from FieldApi. I've created an example based on https://tanstack.com/form/latest/docs/framework/react/guides/arrays#full-example.

You can reproduce the problem by following these steps:

1. Add a person with Name: A and Age: 10.
2. Add a person with Name: B and Age: empty.
3. Remove the person with Name: A.

Currently, the result is:

• Name: B and Age: 10

However, the expected result is:

• Name: B and Age: empty.

I’m not sure if I'm doing something wrong. Could someone please take a look at the code and see if this might be a bug?

Thank you! https://codesandbox.io/p/devbox/crazy-wind-64cdcd?embed=1

I think it's because you're having both controlled and uncontrolled inputs (with value undefined).

Does it happen the same with this? value={subField.state.value ?? ''}

No, with ?? "" I can get the expected behaviour. 🥸
