How to fix react paginate problem by moving from page to another - reactjs

Question

I set up a logic to create pagination in react using data that I fetched from an endpoint API, which contains 5 objects that I displayed in this UI, Then I created a function pageCount that I implemented into my react paginate component, when I click to move to the second page it moved to the last page, next, and previously they didn't work either.
I research a lot to fix the problem but I didn't find any solutions?
Where this problem comes from?
Thank you
function App() {
//states
const [yogaCourses, setYogaCourses] = useState([]);
const [isLoading, setIsLoading] = useState(true);
const [levels, setLevels] = useState([]);
const [level, setLevel] = useState('');
const [pageNumber, setPageNumber] = useState(0);
//Paginate react
const coursePerPage = 2;
// const PageVisited = numberPage * coursePerPage;
const pageCount = Math.ceil(yogaCourses.length / coursePerPage);
console.log(pageCount);
//Track changes on each numberPage and display the data
useEffect(()=> {
setYogaCourses(yogaCourses.slice(pageNumber * 2 , (pageNumber + 1) * 2))
},[pageNumber]);
//To the next Page
const pageChange = ({selected}) => {
setPageNumber(selected);
}
//levelChangeHandler
const levelChangeHandler = ({value}) => {
setLevel(value);
}
//Filter by Levels // stateless
const filterLevels = (level) => {
return yogaCourses.filter((singleLevel)=> level ? singleLevel.level === level : true);
}
//Function to fetch the data from the API
const GetCourses = async () => {
const response = await axios.get(url)
const {data} = response;
return data;
}
//UseEffect to run the function on every render
useEffect(()=> {
const GetCoursesYoga = async () => {
const result = await GetCourses();
setYogaCourses(result);
setLevels(Array.from(new Set(result.map((result)=> result.level))));
}
GetCoursesYoga();
}, []);
//check if the we got response
useEffect(()=> {
if(yogaCourses.length > 0) {
setIsLoading(false);
}
}, [yogaCourses])
if(isLoading) {
return (
<Loading/>
)
}
else {
return (
<main>
<div className="title">
