Hello @bselph116,
My name is Henry Eduardo and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having saving your second password. If you are trying to save it using the notification but it is trying to edit the existing one, I would suggest to manually store it using one of the other methods available on this article.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry Eduardo | Customer Care
