Rank Math SEO plugin – Sitemap issues – Indexing Wrong URLS

Hi, i have an issue with the sitemap of my website: https://freecoder.dev

I used the Rank Math SEO plugin to generate this sitemap, the main problem was that at the indexing phase the crawlers indexes some wrong and unwanted pages that aren’t included into the generated sitemap: https://freecoder.dev/page-sitemap.xml https://freecoder.dev/post-sitemap.xml

Can someone give me a clarification and tell me from where these pages are known if they are not listed into the sitemap? and how to fixe that issue?

Thanks by advance.
