Questions are not being displayed

I am testing the Q&A plugin and having some issues. When browsing to a category, questions are not being displayed (http://itprotv.staging.wpengine.com/questions/categories/aplus/). Browsing to the main questions view displays my site posts instead of questions (http://itprotv.staging.wpengine.com/questions/). The questions are published and are visible if I directly link to them (http://itprotv.staging.wpengine.com/questions/this-is-a-test-question-is-it-working/).

I have disabled CSS temporarily while my designer gets the plugin working with our theme. Even with CSS enabled I get the same results. What is causing my issue? I am running WordPress 3.5.2.
