Detect and fix bugs in JavaScript functions

In this fragment of JavaScript code, an object-service is implemented that stores a list of users and allows retrieving only those whose status matches the current filter. However, the implementation contains a logical error, causing the filtering to work incorrectly.

Your task is to analyze the code, identify the cause of the incorrect behavior, and suggest a fix while preserving the overall structure of the object.

 const userService = {
    currentFilter: 'active',
    users: [
    { name: 'Alex', status: 'active' },
    { name: 'Nick', status: 'deleted' },
    ],
    getFilteredUsers: function () {
    return this.users.filter(function (user) {
         return user.status == this.currentFilter;
    });
    }
};

console.log(userService.getFilteredUsers());
