Thanks so much for your quick reply. That's exactly what I had thought, and I already tried that, but no luck. I've even tried deleting all project and event render files (and emptying the trash), and still no luck. Specifically, I removed the text from the album cover within the effect, then closed FCPX, then deleted all project and event render files (and emptied the trash). But then, when I reopen the project, the old album cover text is back in the effect (in the inspector, where the effect options are located)!
