I moved a handful of documents out of a SharePoint library to a brand new library using the content and structure tool. I added new documents to the new library and wanted to update the properties. However the properties form shows the ORIGINAL properties and not what I added once the document were moved. How do I edit this form? The original properties are irrelevant for the new library.
When you copied the documents, SharePoint probably copied the properties of the existing documents by adding columns to the library. Go to Library Settings and look to see if the extra, unwanted, columns are there. If they are really not needed, then delete them. Be aware that there is no undo for deleting columns.
