Hello,

The default woocommerce shop page is not editable with a page builder. https://monosnap.com/file/EsrDVrD76wZVvu3XmZR59xeO1XjCjz

You need to delete the page and create a new one and set it here: https://monosnap.com/file/wNeK6stzcj3rw4TsclWwVPg9rWAmq5

Alternatively, you can recreate the default Woocommerce product archive page by means of the Woocommerce builder: https://xtemos.com/docs-cat/woocommerce-layouts-builder/?theme=woodmart

Best Regards
