Numerous Contacts Show up as visitors that are actually internal users

When viewing Live View AND History - we have multiple Contacts that show up as the visitor that we know are from our own employees - I've been unable to find why/how they are linked, as the contacts aren't even currently used or active contacts. 

How do we disconnect the internal company users from being associated with these contacts that continually show up on our website visitors?
