Problems with Sitemaps on WordPress Multisites

Hi,
I have a multisite made in this way:

– domain.com
– domain.com/it

What I see is that the first website shows without problems the sitemap at:

domain.com/sitemap_index.xml

But the second site doesn’t load a sitemap.

Instead, the Yoast Interface shows that the URL of the second site sitemap is this:

– domain.com/sitemap_index.xml

Then Yoast says that the sitemap for the second website is like the sitemap of the first website. This sitemap is not loaded or visible. But, in any case, it should be different, and be like this:

– domain.com/it/sitemap_index.xml

Is it a bug?

kind regards

G. Aloe
