Redux Toolkit | createSlice | bugRemoved action dispatch not working

Redux
1

I’m not sure why the bugRemoved action is not working. My code as below.
I thought the last state would have 2 bugs only, but it still has 3.

import { createSlice } from '@reduxjs/toolkit';

let lastId = 0;

const slice = createSlice({
	name: 'bug',
	initialState: [],
	reducers: {
		bugAdded: (bugs, action) => {
			bugs.push({
				id: ++lastId,
				description: action.payload.description,
				resolved: false,
			});
		},
		bugResolved: (bugs, action) => {
			const index = bugs.findIndex((bug) => bug.id === action.payload.id);
			bugs[index].resolved = true;
		},
		bugRemoved: (bugs, action) => {
			bugs.filter((bug) => bug.id !== action.payload.id);
		},
	},
});

export const { bugAdded, bugRemoved, bugResolved } = slice.actions;
export default slice.reducer;

index.js

import configureStore from './store/configureStore';

import {

    bugAdded,

    bugRemoved,

    bugResolved,

    getUnresolvedBugs,

} from './store/bugs';


const store = configureStore();

const unsubscribe = store.subscribe(() => {

    console.log('store changed', store.getState());

});

store.dispatch(bugAdded({ description: 'bug1' }));

store.dispatch(bugAdded({ description: 'bug2' }));

store.dispatch(bugAdded({ description: 'bug3' }));

store.dispatch(bugRemoved({ id: 1 }));

console.log(store.getState()); //I would have thought the last state has 2 bugs but it still has 3.
