You are talking about “pin to bottom of browser window”.
All your other pages are behaving normal because the actual page is longer than your browser window you have open. With your Contact Us page your page is far shorter than your opened browser window, hence the white empty space between your page and the bottom of the browser window.
Just lengthen your Contact Us page and it will fix the issue!
