@Jeff Davis I found something weird in list views today and going to open a case.  We have renamed the owner field on most of our records to be Assigned Banker.  

When I try to add who the Assigned Banker is to our Accounts List view it's showing up as Account Owner Last Name and First name rather than Assigned Banker First Name and Last Name.  Is this expected?  

I checked it's happening in classic too.  So I know it's no really related to lightning, but it's list view related.
