Let's make sure we're all on the same page regarding the terms you're using here:
You
produced a video to 4K, and when you finished and went back to the Edit page, PD automatically loaded the produced clip into your
Media Library. It's
not on the timeline (nor will you put it there), but PD gives you the shadow files prompt because a high resolution clip has been imported.
You can click No on the prompt, or go to Settings and disable shadow files, whichever makes the most sense for you.
Nothing has changed on your
timeline, and you're free to make any new changes you want or save the project as is.
If you don't want the produced clip in your library at all, you'll either have to right-click on and choose Remove from Library or save the project before producing and then close PD after the producing is finished. There is no way to stop PD from automatically adding the produced clip to the library.
