problem with change legal name

[giveme]

I have a question how to change the legal name  I tried to do it through the instructions that were in the options but it failed  I want to change because I did not give the middle name that I have on my bank account therefore I cannot link my paypal account with my bank account  in the options of changing the name and surname, he adds his identity document but nothing happens

You can submit a request to change the name on your Personal account for a typographical error or a legal name change. We’re unable to change the name on a PayPal account to a different person's name.

To change the name shown on your account:

1. Click settings (icon next to log out)..
2. Next to your name, click Edit.
3. Click the type of change you want to make and follow the instructions:

• Change your legal name.
• Update your name.
• Make a minor correction. You will be able to fix a typo of 1 or 2 characters only once.

If you're not fixing a typo, you'll be asked to provide documentation to support your name change (i.e. copy of your photo ID and your change of name certificate).

There is also no button to confirm the documents
