Emails returned that are not connected to the Constituent

I originally asked support to look into this as it appears to be a data issue in RE, see case #018497364. I am seeing some emails in the constituentList endpoint that lack types, ids, and other fields. This caused an error on our end, as we expect them to line up with the schema in the documentation. When checking with the client whose data I found this issue in, they mentioned that the user did not have any emails in their profile. Also turns out if I query that user specifically, I don't see the email. I am loathe to include client specific details in a fairly public forum, but the specifics are in the support case if a Blackbaud staff member would like to look...I fail to see how any other API users would be able to assist.

@Ray Bergman Any chance you could assist me here? Happy to provide more details in a private capacity.
