[LE] Can't Load Follower ESP in NPC Editor

[Greihart]

First of all, I'm sorry if I have bad english because english isn't my native language.

 

This is my 1st time trying to make a mod with Creation Kit, and I'm working on a Follower Mod, this is the character I would like to try to make mod.

 

 

To make it, I followed the way based on this tutorial, since I only have ECE and can't use Racemenu.

I have finished every progress and done my esp file, as u can see from this screenshot this was the last step of work with Creation Kit.

 

 

 

 

But then I got stucked when trying to load the follower file in NPC Editor, it shows like this.

 

 

 

 

I don't know what kind of mistakes did I do since I could progress till the last step of Creation Kit smoothly. Then I tried to test it out in the game without countinuing the next step since I had problem with NPC Editor, but then it causes my game crash.

Anybody can help with this? Especially the one who create follower with ECE?
