First featured product images are stretching

[CarolineNS]

This didn't happen before, but now my first images in my features collection / product are being stretched. Original images are squared. I've tried modifying from the theme customiser but there's no option and I know almost nothing about coding.

Any help is appreciated.

Hello @CarolineNS 
I have checked your website, and it is working fine.

Thanks for your reply. The problem is present in Chrome and Edge, Firefox and Safari work correctly. Even the price is showing in different currencies.
