I have inspected your site and pages. The CSS issues are coming from your themes CSS. If you are a familiar with customizing themes and CSS, please inspect the classes of the corresponding attributes and write CSS according to your needs and do not forget to remove the sidebar on the dashboard page.
Sorry for the inconvenience.
We have tested our plugin with standard WordPress themes. So it should not break. If your theme is not matching to the plugin and you can not tweak the CSS yourself, you should hire a developer.
I am also having CSS problems. My support request has been outstanding almost a week. No response at all. The product and support are bundled and so far the support has been lacking. Do you guys plan to offer any support and respond to the requests here. We paid good money for this product. in this age of the internet bad reviews on the blogsphere could be damaging for your guys. Please try to honour the contract and provide the support people are requesting.
