image aspect ratio appears to be applied inconsistently

Hello everyone,

In one category of goods, i use images in 3:2 aspect ratio.
I am testing additions to this category and the images appear to be treated differently.
Can anyone suggest why this would be the case ?

Here is the live site, where the category images are 3:2 with consistent display
https://flycrew.co.uk/?product_cat=freemans-meaty-treats

Here is the test site, where the category images are 3:2, but the two additional images are displayed 1:1
https://flycrew.musetopia.com/?product_cat=eating-in

Any help would be appreciated.

Thanks,
Alex,
