You are only allowed x2 paypal accounts if x1 is personal and the other x1 is business, if you have 2 of the same type you risk them all being limited. So your best bet would be to contact customer services to see if they can help you locate the surplus and close them.
Contact options for Paypal are accessed by clicking help/contact bottom left of Paypal pages...
1. Paypal phones are slowly re-opening and increasing in numbers (you can use the guest option if you can't log in). 2. Live chat is also randomly available. 3. You can send them a message, during business hours you may also be able to message whilst logged out. Or 4. Have you considered contacting Customer Service via Facebook or Twitter? You can send them a personal message from their Facebook or Twitter pages. It's: https://www.facebook.com/PayPal and @AskPayPal for Twitter.
