Product Descriptions in Greenmart

Hello Guys!
Currently replacing my old website with Greenmart and love the theme!
I have an issue…

Product descriptions…
The theme has a default text with an image.(see image)
I can edit the product descriptions through the backend on each product.
When i update this, it does not replace default text in the product descriptions.
I take it there is another place to edit this text, as every product i have has a different description.
Any help please.
