sortDirection prop of TableCell doesn't work - reactjs

Question

I have a table with items. I use cookies to save them. Also, I have two buttons (increase and decrease). When I press them to change qty it works, but it also puts the item's row to the bottom of the list. I need to keep them in the same position where they are. I used sortDirection prop to TableCell component to make an order, but it also didn't work. Please help update the code so I can keep items in the same position.
Thanks in advance.
export default function CartItemsTable() {
const [cookies, setCookie, removeCookie] = useCookies();
function IncreaseQTY(article) {
var newCookie = cookies[article];
newCookie.qty++;
setCookie(article, newCookie, {
expires: new Date(Date.now() + 604800000),
});
}
function DecreaseQTY(article) {
var newCookie = cookies[article];
newCookie.qty--;
if (newCookie.qty === 0) {
removeCookie(article);
} else {
setCookie(article, newCookie, {
expires: new Date(Date.now() + 604800000),
});
}
}
return (
<TableContainer component={Paper}>
<Table sx={{ minWidth: 650 }} >
<TableHead>
<TableRow>
<TableCell >Name</TableCell>
<TableCell sortDirection="asc" align="center">Code</TableCell>
<TableCell align="center">Price</TableCell>
<TableCell align="center">QTY</TableCell>
<TableCell align="center">Total</TableCell>
</TableRow>
</TableHead>
<TableBody>
{Object.keys(cookies).map(function (key, index) {
return (
<TableRow
key={index}
sx={{ "&:last-child td, &:last-child th": { border: 0 } }}
>
<TableCell component="th" scope="row">
{cookies[key].name}
</TableCell>
<TableCell align="center">{cookies[key].article}</TableCell>
<TableCell align="center">{cookies[key].price}</TableCell>
<TableCell align="center">
<ButtonGroup
variant="contained"
aria-label="outlined primary button group"
>
<Button
onClick={() => {
DecreaseQTY(cookies[key].article);
}}
>
-
</Button>
<Button variant="text" disableRipple={true}>
{cookies[key].qty}
</Button>
<Button
onClick={() => {
IncreaseQTY(cookies[key].article);
}}
>
+
</Button>
</ButtonGroup>
</TableCell>
<TableCell align="center">
{cookies[key].qty * cookies[key].price}
</TableCell>
</TableRow>
);
})}
</TableBody>
</Table>
</TableContainer>
);
}
Before I press the button
After I press the increase button, first line went to the bottom
Update
I guess this problem can be occurred because of the cookies order or even related to react-cookie package, so I added console.log(cookies); to IncreaseQTY function. After a couple increasing it starts to show this way
