Blueprint Migrate failed. Could you help me?

I downloaded this project.

And I wanted to move the fog sheet, so I moved all the contents.

But it doesn’t work the same way. I checked the inside of the blueprint, but I couldn’t find any difference. They moved with the engine turned off, and others function normally.

How can I activate the fog sheet?

My Unreal version is 4.27.2.

I succeeded because I set the default language setting to English.
