Can't assign widget to woocommerce page?

Hi Team,
I am building an online store site basic on theme University. When I try to assign widgets to a specific page, I find I can't use "Add page" button. For example, I want to assign "WooCommerce Product Categories" to "product categories" page only. I choose "product category" from the page list in "widget rules" and click "Add page" button. But nothing happen. The same problem happened when I choose "shop" page. It works fine if I choose other page such as "Homepage" or "Author". Can you tell me how to fix it? Can you tell me where are the pages list from? There are neither "Pages" nor "page template". The page list as follow:

Homepage
BuddyPress Activity
Page
Post
Category
Category with descendants
Tag
...
Search page
404 page
Product category
Shop

Thanks

Hello,

Unfortunately University theme doesn't have support for WooCommerce, so widget rules like "product cateogry" or "shop" are probably added by a mistake and can't work properly. You can compare the widget rules files with some of our themes with WC support and add mofiications, but it's a lot of work.

Will be easier i think to use i.e. widget logic simple plugin and conditional tags from woocommerce:
