EnhancedInput Project Setting "bRegisterWithUserSettings" dont work

In the project settings of Enhanced Input, the default mapping context’s’ bRegisterWithUserSettings’ does not work:

The default mapping context here is called in UEnhancedPlayerInput.

But it seems that there was no call to Register Input Mapping Context.
I checked using the blueprint and confirmed that there was no automatic registration.

Only manually add Mapping Context and select options ->Notify User Setting=true

Is this a bug?
