category_slug does not work

Hi,

I have a problem with the posts_carousel and category_slug. I have tested with your demo data, and it does not work. If you put in a category_slug on the “home” page in your demo, the carousel is empty.

Is it a bug, or am I missing something?

[posts_carousel heading="Test" post_type="portfolio" category_slug="agv" order_by="date" order="ASC" limit="10" meta="no" excerpt="no" excerpt_char_limit="72" exclude_current="no" width="four columns" scroll_by="4"][/posts_carousel][column width="1/3" position="first" ]

Best Regards, Christian
