Moving Files Issue

We have a user that is trying to move a file they created (owner) from their own folder to a group folder which she has been given Editor permissions.  She can upload to this folder just fine, but cannot move / copy files from any other location in Box that she has owner permissions to.  This destination folder is nested 3 layers down from the root, that this user only has Viewer permissions on the rest of the way up.  No other user has reported this issue, but no other user has their permissions set this way.  Any assistance would be appreciated.
