Answer 1

I finally did the old school way of disabling all plugins and enabling them one by one as suggested by the Studiopress Support team and found out that 'Genesis Simple Comments' plugin was causing this problem.

Nick, the author of the plugin said that it needs an update, so for now the issue is solved.
