How can two different accounts had the same email connected?

We recently needed to change passwords for two different accounts, and both had the same email connected to them. The username for one was stevenhenry74, and the other username provided was lcalhoun@ffa.org.

Both of those usernames had different data, but because the passwords got changed (to the same password), the data from the lcalhoun@ffa.org username seems to have disappeared. How can I access that?

Thanks in advance.

There is an email validation when you create an account. However, you've changed the email address of the skappus account. For some reason, the system doesn't validate it allowing you to proceed. 

To fix the problem, the email address of the other account (stevenhenry74) needs to be changed. Please designate a new email address, and we'll do it for you so you can reset and access the account. 

Note, you need to log in using the username instead of the email address. This will also help since you know the passwords.
