Hello,
I tried using FireFox and Chrome on Android and was unable to replicate the issue with a fresh install of BoldGrid with Pavilion. Have you tried clearing the cache in your browser to see if you are still getting the issue? If you can provide us a link to your site we can also try and see if we can replicate the issues on your site and see if we see any conflicting CSS or plugins showing.
Best Regards,
