Thanks for visiting us here, alpinegrove.

Right now, we have an ongoing investigation about the PayPal bank getting an error message "Something of your information isn’t correct. Please try again" when updating the account. If this is the exact error you are receiving, then our engineers are aware of this issue. They working on fixing this error as soon as possible.

Once the issue is resolved and you're able to update your PayPal account, you may see some duplicate transactions. What you can do is exclude them by following these steps:

3. Click the Exclude button.
