[Plugin: WordPress Download Manager] Shortcode / Sidebar Issue

When I use the shortcode to display a category, the sidebar on the page is pushed down the page into the footer area. (This does not happen when I use the shortcode to display individual downloads)

I’ve also noticed that the shortcode for categories uses curly brackets “{” “}”, instead of square brackets “[” “]”. Could this be the issue?
