Sitemap including pages which have been deleted a long time ago.

Hi everyone

thanks to Google Search Console we realized that the Sitemap created with SEO plug-in is containing pages which are no longer existing, have been deleted (and are no longer in the trash bin or in the drafts) and were created while being localhosted but were never uploaded to remote. What to do to correct it? We are talking of pages which were canceled like 6/7 months ago. Some were created with WPML and were then cancelled because a given language was not chosen to be in the final website.

Furthermore, we realised that it is often not detecting images even if Google Search Console can correctly crawl the pages.

Any suggestions?
