Product Description doesn´t show

Hi,

I my site is http://www.citysafe.cl and I have the Storefront theme.
The product description doesn´t appear on the product page under the image. Curiously if I write on the short description that text does appear, but under title, which makes the “Buy” button go down and that may have a negative impact on my convertion…so I don´t want to do that.
Can you help me?
