SharePoint Library - Invisibile Metadata

Hi All,

Strange issue I'm running into on a library

Left is my Admin profile where files are grouped by WF Year (metadata column)
Right is a couple users with the issue where its showing Unassigned due to blank Year and Month 

I've exported the data from both accounts and both have the Year and Month

Tried going to Properties on User account and the Year field appears like this

...very strange, any help would be appreciated :)
