Vim-airline generating gaps at bottom

Question

I installed the Vimair line using Vundle, as below,

Plugin 'vim-airline/vim-airline' Plugin 'vim-airline/vim-airline-themes'

But the status bar is generating some of the margins at bottom. I don't know how to fix this, as I am a new learner. A sample screen shoot is shown below.
