Codesandbox/Expo snack

https://codesandbox.io/s/react-hook-form-controller-issue-forked-2dm88j?file=/src/index.js

Steps to reproduce

1. Go to 'index page'
2. Click on 'APPEND'
3. type something in first name and last name inputs
4. Click on PREPEND
5. Click on SUBMIT

You can see correct values in form values but controller does not update that

Please let me know if there is any mistake on my part.

Expected behaviour

• New inputs should be added at the start of fieldArray
• Errors should only be shown for empty inputs.

This issue seems to have occurred between versions 7.26.0 and 7.26.1.

you can see that same code works fine in 7.21.0 -

Hello, I noticed that you use key={index} not item.id, which is a unique field identifier. It functions well now.
