Why profile data from react redux firebase isn't loaded?

I'm trying to load profile data via react redux firebase, but it doesn't work.

This is my function to create a new user:

firebase.createUser({ email, password }, { firstName, lastName })

That's the way I'm setting my store:

const rootReducer = combineReducers({ 
    auth: authReducer, 
    firestore: firestoreReducer, 
    firebase: firebaseReducer 
})

const store = createStore(
    rootReducer,
    compose(
        applyMiddleware(thunk.withExtraArgument({ getFirebase, getFirestore })),
        reduxFirestore(firebase, rrfConfig)
    )
)

Where fbConfig is config from firebase and rrConfig is:

const rrfConfig = { userProfile: 'users', useFirestoreForProfile: true }

After that I render it:

<Provider store={store}>
    <ReactReduxFirebaseProvider
        firebase={firebase}
        config={rrfConfig}
        dispatch={store.dispatch}
        createFirestoreInstance={createFirestoreInstance}
    >
        <HashRouter>
            <App/>
        </HashRouter>
    </ReactReduxFirebaseProvider>
</Provider>

What could be wrong? Firstname and lastname is in firestore database, but it doesn't load.
