How do I delete NPC's from an .esp in TES Edit?

[Devorax]

*EDIT: Never mind... when I searched 'Astrid' TES Edit was apparently jumping to the vanilla Skyrim's section, and not the Ultimate NPC Overhaul 2 section...

 

I'm sick of trying to mess around with load orders, and I really don't like the way Astrid looks in the Ultimate NPC Overhaul 2 mod. I tried overriding it with an Astrid replacer, but ingame, she looks like a disgusting amalgamation of both mods. 

 

What I want to do now is delete Astrid from the Ultimate NPC Overhaul 2 .esp so the game will be forced to use the Astrid replacer I want. How do I do that in TES Edit? I opened up TES Edit, searched 'Astrid' in the Editor ID box, and left clicked her name (under the Non-Player Character (Actor) category)  to highlight it. Pushing the Delete key does nothing. So how do I get rid of her?

 

Thanks.

Right click --> Remove.

Right click --> Remove.

 

This but you would also need to remove or overwrite the accompanying nif assets in facegendata for both textures and meshes (so take note of the editorID number before you remove it
