'category_slug' not working.

Hello

I am trying to use the shortcode with ‘category_slug’ to display the items for that certain category in a page.

However when I enter the shortcode in a page it displays nothing on the page even though there are items in that category.

Example:
[rx_aeolus_three_cols category_slug=”web-design”]

How can I solve this?
