Product image ratio

I use square images 1200 x 1200 px for my products, but when I add a product to the cart, the image is displayed in 500×667 px in the side cart::

In my theme settings (Blocksy), the product thumbnail ration is set to 1/1:

How can I fix this and make the images in the side cart display square?

You can try to add something to the cart to check this, for example https://splitted.space/en/mechanical-switches/outemu-mx-switches-brown-tactile
