Missing WooCommerce Products in Sitemap

Hi there,

I am using XML Sitemap Generator for Google 4.1.11 and in the FAQ’s I could read that WooCommerce products can be handled in the sitemap. But my sitemap is not including my products:
https://amazing-handmade.de/sitemap.xml
(Only product categories are available in the sitemap)
I am using standard settings, but maybe someone can explain which setting I may need to include normal WooCommerce products.

Thanks, Alex.
