Ionic export running locally does not work with chrome debug tools

I am new to ionic. I created a simple app with creator and exported it and am hosting it locally. It runs as expected. However, if I load or reload the page with chromes developers tools open in the browser page, the fixed bottom nav bar appears on top just below the page headers. Is this a known issue? Is there something I can configure or change to make the page work properly when it is loaded with the chrome debug tools open?
