Hi there, had the same problem as you, here is a post explaining what’s happening:

Further down the page user called VlooMan has provided a plugin to act as a temp fix. It works like a charm. So far used it on several of my sites.
It looks like there has been an extension developed but it will cost $29

I’m experiencing the exact same issue. A quick solution for this has been to create pages, set the access restrictions, then use the WooCommerce shortcodes to pull in the category I wish to display.
e.g. [product_category category=”category_name” per_page=”12″ columns=”4″ orderby=”name” order=”asc”]
I would really prefer not to use this method but it’s the only way I’ve been able to get it to work.
