Setting Problem

Hello,

I installed the plugin and my main purpose is to add Title, Description on all pages.

Question
1: What changes I have to make in default title tag & Tagline boxes which comes under “Settings > General”

I am asking this because when i am deleting the text from both boxes then home page title tag showing blank and when i add something then its shows on all pages title tags.

Thanks
