Identify whether the item is already in the library
Suppose an authorised local video is already present, but its plot or title was corrected in the associated NFO. The task is to revise an existing library record. It differs from adding a newly copied video that Kodi has never scanned. Write down which state applies before running a broad library operation or assuming the text edit was ignored.
Follow the documented distinction
The official Updating or removing videos page says that changes inside an NFO for an existing title are not applied by the add-new-items operation; one of the refresh methods is needed. That is a specific workflow distinction. It does not imply that the whole library is corrupt or that a factory reset, decoder change or account renewal is required.
Test a single known correction
Work on a backed-up metadata file and make one recognisable, legitimate correction. Refresh the intended item using the current documented route, then inspect the displayed result. If the wrong title is selected, stop and verify identity before applying the same operation broadly. A personal home movie and a commercial film can have similar names, so preserving the original record makes an accidental match easier to reverse.
Use a focused support report
If the correction still does not appear, retain the NFO type, source settings, Kodi version and exact refresh action. Share only a small sanitised example when needed. Saying that a full scan completed is less useful than showing which operation was used on the existing item. This case explains metadata refresh and does not claim that editing an NFO changes the underlying video or a remote IPTV catalogue.
