Multisite sitemap seems not working

Hi. I installed this plugin as it seemes to be a good sitemap creator for multisite install.

Unfortunately it does not seem to create more than the main domains sitemap with an addition the subdomains ID. I do need it to use the mapped domain in the sitemap.

I have only acitvated this plugin on one of the subdomains mapped to https://wesenlund.se/sitemap-11.xml and there is a sitemap with links to the subdomain only. How to get passed that problem?

The page I need help with: [log in to see the link]
