Unfortunately, as per forums rule, I/we cannot ask you to share your private data on a public forum. Another way could be relevant screenshots highlighting the issue. OR, would it be possible for you to create a staging environment activating only the required plugins and share the link?
If all the above options are not immediately possible, please check the following possible fixes:
1. Check whether the source of the sitemap shows you the data you would expect in an XML sitemap. Not sure how to see the source code, follow the steps in this article.
2. If you have a cache plugin or server side cache, please flush the cache. If the issue remains, please disable and re-enable the sitemap feature (steps here) to force a cache reset. If you are not sure how to clear caching from theme/plugin please speak to those authors. If you want to clear cache from the server, please speak to your host provider. To clear the cache from a browser use this guide: https://kb.yoast.com/kb/how-to-clear-my-browsers-cache/
3. Open the sitemap and the sitemap stylesheet in Firefox to see if any errors display. If an error displays, please read this article about common sitemap errors.
4. Yoast SEO uses the WordPress site URLs to generate the sitemap. In rare cases, these URLs may not match the preferred URL format of your site. Go to Admin > Settings > General and make sure the correct Site Address and WordPress address match the sitemap URL you are trying to view.
Can you inform us of the results?
