Sidebar Widget Overflow

I am trying to use shortcodes, via text widget, in the sidebar. Specifically the testimonials, list, and staff shortcodes.

However, all the content (specifically whatever is added via shortcode) is bleeding over the widget container.

(I know that I can use the testimonials widget, but since I want to select specific categories of testimonials, the widget doesn’t quite do the job.)

I’ve tried placing the code in a column, in a table, and by itself, with and without the widget’s “automatically added” paragraphs, and nothing seems to work.

I am using the Aegaeus theme. Here is a link to a page on the site which displays the issue:

Your help would be greatly appreciated. Thank you!
