Offset not working

I am trying to display 4 posts in 4 columns. The theme has the ability to make each widget 1/4 of the width – all the css is already done for that – so I wanted to use 4 widgets each displaying 1 post. When I add these shortcodes to the Custom HTML widget – I get 4 articles – but they are all offset by 3. 4 of the same articles.

Using the Corporate Pro Genesis child theme.

widget 1: [display-posts image_size=”portfolio” include_excerpt=”true” posts_per_page=”1″ category_id=”7″]
widget 2: [display-posts image_size=”portfolio” include_excerpt=”true” posts_per_page=”1″ category_id=”7″ offset=”1″]
widget 3: [display-posts image_size=”portfolio” include_excerpt=”true” posts_per_page=”1″ category_id=”7″ offset=”2″]
widget 4: [display-posts image_size=”portfolio” include_excerpt=”true” posts_per_page=”1″ category_id=”7″ offset=”3″]
