Can't delete Niagara Components inside BP?

Hi, I’ve added a couple Niagara components to a BP but decided I don’t need them anymore. Right-click > delete is greyed out, del key has no effect and can’t delete from the Variables > Components list either. It is not inherited. I tested on a blank actor > add niagara component and I can delete it.

Am I missing something? I can delete other components (Camera shake, collision objects, etc) but not the Niagara. There are no references to them in the BP code.

Seems to be because I copy/pasted the components in from another BP. Had to re-create my BP to get rid of them.

isnt there any easier way to do it? i came across this problem recently

What version are you using? Upgrading to 5.2 or 5.3 seems to have solved this issue for me.

currently using 5.4 and unable to delete child components of a blueprint in blueprint editor viewport.
The children are not dependant, but even the other blueprints for reference have the options checked to allow editing in children, so why cant i delete them?

A work around is i’m throwing them all under another child in the blueprint and removing the meshes associated, but that creates a null mesh error. Seems i’ll have to rebuild from scratch, which will take a long time.

We need the ability to force delete.
