5.1.1 PCG Actors Vanished But Results Stuck In Landscape

I’m completely baffled and hope somebody can please assist. Was working on this large landscape for a flying cinematic and added PCG to scatter various rocks and bushes around.

I’m super careful about organization and created a dedicated folder for the PCG in both the outliner and in my project.

However, while the scattered meshes are still in the level/landscape as seen by the attachments, the PCG is not in the outliner, or, in the file whatsoever.

Even the folder is gone from file explorer. I can’t edit/delete the PCG, nothing.

Any clues? I’d like to remove those meshes but can’t.

Thanks in advance for any help.

The two images show the meshes and missing pcg in outliner, and my filters for outliner.
