How to remove PCGWorldActor or PCGPartitionActors?

I created a pcg volume then partitioned it to the landscape world partition however now i cant remove it because the delete button is greyed out, have also tried finding the actor in the local files and removing that directly but it still persists, have also try removing the pcg volume as well as clearing it but no matter what this foliage still persists. Any ideas on how to remove this?

You can try to do it it via Tools → PCGFramework → Delete PCG Partition Actors
Or use EditorUtility for it. For example - https://www.youtube.com/watch?v=aU3h3vzgIB0

Thanks for that, it worked like a charm
