Pencil Icon in STAGING/Invalid Extended Attribute

System

What does it mean when a file in the STAGING area appears with a pencil icon next to it (as if it's somehow been modified in STAGING)?

In this case the file in STAGING is a templated output file but for some reason includes the extended attribute that indicates it's a DCR (TeamSite/Templating/DCR/PrimaryDocumentType). The corresponding file in the workarea does not have this extended attribute.
