Prestashop 1.7 subcategory banner is too small

[samihasayed]

I have prestashop 1.7 site with page builder base template, I'm trying to add a subcategory banner image with size 200x900. I have change the banner size from the images preferences in the back office, but it is always showing a very compressed picture by the right hand side of the banner in a very small size.

I tried fixing it by all ways, with no luck.

I'm not a great developers to change the code, so I'm seeking your support please.

Here is my site, and the subcategory page: https://www.tbatsolutions.com/OurPetZone/index.php?id_category=4&controller=category

Thanks in advance
