Interesting that you don't remember what the second destination was
Anyway, if you haven't changed it, then my guess is that the media onto which you were writing is no longer available (e.g., a disconnected external drive or network volume). Perhaps that'll help you remember what it was. Also, did you save your ingest settings as a preset (lightning bolt)? Then the path will still be in that file. Just locate it and open it in an editor (it's an XML file).
