If you are lucky then it is just an ALV grid display width restraint. Double-click the record to see whether more is displayed?
If not, then the recording is truncated. Is the length 225?
Within the application you can also display the log of documents in tcode OA_LOG_VIEW_DOC. For the download option you might have to use the RAL (Read Access Logging) option - though mind you that might be truncated as well. Uploads also have a limit - the file path cannot be too long in the directory to reach it, otherwise the ABAP typing of the field might not reach it.
