XML Sitemap not recognized by Google

I’m using WordPress and Woocommerce with the (in my opinion) best plugins Yoast SEO and W3 Total Cache. Bu I have some issues with the sitemap, Google keeps sayin the sitemap (index) is empty.

W3 Total Cache settings:
1. The W3TC Extension ‘WordPress SEO by Yoast’ is installed and active

2. Minify > Advanced:
2.1.
sitemap(_index|[0-9]+)?\.xml(\.gz)?
sitemap(_index)?\.xml(\.gz)?
([a-z0-9_\-]+)?sitemap\.xsl
[a-z0-9_\-]+-sitemap([0-9]+)?\.xml(\.gz)?
sitemap_index\.xml
2.2. Reject user agents: googlebot

3. Page Cache > Advanced > Never cache the following pages:
wp-.*\.php
index\.php
sitemap(_index|[0-9]+)?\.xml(\.gz)?
sitemap(_index)?\.xml(\.gz)?
([a-z0-9_\-]+)?sitemap\.xsl
[a-z0-9_\-]+-sitemap([0-9]+)?\.xml(\.gz)?
sitemap_index\.xml

4. Browser Cache > 404 error exception list:
robots\.txt
[a-z0-9_\-]*sitemap[a-z0-9_\-]*\.(xml|xsl|html)(\.gz)?
sitemap(_index)?\.xml(\.gz)?
[a-z0-9_\-]+-sitemap([0-9]+)?\.xml(\.gz)?
sitemap(_index|[0-9]+)?\.xml(\.gz)?
sitemap(_index)?\.xml(\.gz)?
([a-z0-9_\-]+)?sitemap\.xsl
[a-z0-9_\-]+-sitemap([0-9]+)?\.xml(\.gz)?
sitemap_index\.xml

5. User Agent Groups > [I’ve created a new group name named googlebot:
Enabled [checked]
User agents: googlebot

6. Cleard the cache many times, waited many days, no results, Google keeps saying my sitemap is empty.

Do you have any other suggestion, cuz I don’t know what to do anymore.
