Помогите пожалуйста найти ошибку, ошибка заключатся в том что происходит отрисовка 2 одинаковых массива 'users' вместо 1

1.Редьюсер :

let UsersState = {
    users: []
}


const UsersReducer = (state = UsersState, action) => {
    switch (action.type){
        case FOLLOW:  return {
            ...state,
            users: state.users.map(user => {
                if (user.id === action.userId) {
                    return {...user, Followed: true}
                }
                return user;
            })
        }
        case UN_FOLLOW:  return {
            ...state,
            users: state.users.map(user => {
                if (user.id === action.userId) {
                    return {...user, Followed: false}
                }
                return user;
            })
        }
        case SET_USERS: return {
            ...state,
            users: [...state.users, ...action.users]
        } 
            
        

        default : 
        return state;
    }
}

export default UsersReducer;


const FOLLOW = 'FOLLOW';
const UN_FOLLOW = 'UN_FOLLOW';
const SET_USERS = 'SET_USERS'


export const SET_USERS_AC = (users) => ({type: SET_USERS, users})
export const FOLLOW_AC = (userId) => ({type: FOLLOW, userId})
export const UN_FOLLOW_AC = (userId) => ({type: UN_FOLLOW, userId})
