Needing to delete "blank" person record

Content

Employee has two active "records" in Core. One is fully populated, including assignment. The other is completely blank, outside of having "person" information such as name, address, email, etc. I initially thought I would cancel the work relationship, however it was realized that the record doesn't have a work relationship to cancel. 

I am needing help on how to delete the "Blank" record and to also understand what is causing the issue. 

As an FYI, I dont even see the "Manage employment" tab, to where I would attempt to "delete" person.
