react redux reducer does not work properly

You need to recreate the items object, with active set to false for the items that do not match the clicked items.

case actionTypes.SET_ACTIVE:
      const editItem = accounts.map((item)=> item.id !== action.id ? {...item,active: false} : {...item,active: true})
      
      console.log(editItem)
          return {
            ...state,
            accounts: editItem
          }
    default:
      return state;
  }

PS: If possible , you should maintain a local state for each of your checkboxes and set that via a toggle function and then at some later point you want to dispatch. I dont know, how you designed the application , but just an additional suggestion!
