Sitemap not updating

Hello team rankmath,

Recently I have deleted the previous webstories which were of no use and total 272 webstories were published. So after deleting we had total around 50 stories left. But the sitemap still shows 272 links in it. And all the new webstories published after deleting the previous one’s aren’t included in the sitemap.Currently we have a total of 88 stories published. Check and let us know what’s the problem, we’re facing huge loss from it. Reply as early as possible.
Thanks.
