Cols not updating after select list changing

Hello,

I use react Grid-layout, thanks to the developers for this superb work.

On the other hand, I do not understand why the number of column does not update in my table.

In fact, this.props.cols.lg is either 17 or 24.

When it's 17, my table is displayed correctly. On the other hand, when I choose a period with 24 columns, my columns are placed one below the other from the 18th.

this.props.cols.lg to the correct value (17 or 24) but my HTML page does not update to the design level.

This is the right table

and the bad table

IMPORTANT :

this.props.cols.lg=loopValue+1;

contains the right value (17 or 25 cols) but it does not apply to my site.

Thank you in advance for your help.

Here is a part of my code:

import React, { useState, useEffect, Fragment } from 'react';
import { WidthProvider, Responsive } from "react-grid-layout";
import ReactTooltip from 'react-tooltip';
import _ from "lodash";
import { Button, Container } from 'react-bootstrap';
const ResponsiveReactGridLayout = WidthProvider(Responsive);
import { Responsive as ResponsiveGridLayout } from 'react-grid-layout';
