Thumbnails not displayed at desired size

-- HikaShop version -- : 3.2.1
-- Joomla version -- : 3.8.2

Hi,
I wanted to change the Thumbs from 180x180 to 225x225 but they are still displayed at old setting (180).

I deleted caches, deleted thumb folders but nothing change.

Am I missing something? I need the thumbs to be bigger for my design.

Changing force image size (yes/no) does not solve it.

I see part of the problem also with design is the hardcded css in page like:
#hikashop_category_information_menu_247 .hikashop_product_image { height:225px; }
#hikashop_category_information_menu_247 .hikashop_product_image_subdiv { width:225px; }
I need to get ride of that. Please let me know how.
