Hello,
Thank you for contacting the support and we regret the inconvenience caused.
Indexed, Not Submitted in Sitemap, it is not an issue, it only means that Google has already indexed the posts/pages but not through the sitemap.
It is possible that Google is crawling and indexing the post through other means like the internal links on your website and not through the sitemaps. As a result, the crawl budget for your website is exhausted, and Google is not able to discover the URLs through your sitemap.
As long as the URLs are getting crawled and indexed, there’s nothing to be worried about.
However, as for a lower number of URLs included in the sitemap, please follow the below steps and see if that helps:
1. Flush the Sitemap cache by following this video screencast:

2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

3. Clear your website and browser’s cache and check the sitemaps again.
If the URLs are shown, you can remove all the sitemaps from your Google Search Console account, and submit only the main sitemap: /sitemap_index.xml.
Hope this helps.
Thank you.
