Yes it’s normal.

It was only designed to show the core WordPress content such as posts, custom posts, pages, categories, tags and archives.

Anything beyond what’s mentioned above isn’t shown.

I don’t know how to where WooCommerce saves it’s data if there isn’t an api or anything that I can use to get the WooCommerce data then unfortunately it’ll never be included as otherwise if I hack something together to make it work whenever they make a change it’ll potentially break my plugin.
