Ah, I see. I would create a copy of the file (CTRL+C on the Client screen) and test it out on the duplicate (the duplicate should also copy your efile history). Then if you see it work right, delete your whole copy file and then do it on the live file. If you can't cherry pick deleting the failed one, I'd either decide to live with it or call Support (but only let them touch and troubleshoot the copied file).
