zoom not working properly

dear support,
I follow the setting insctruction for the zoom magnifier but the result is strange and not correct.
my product image becomes very big and I see the zoom screen inside smaller…

one example is :https://ozio.neywa.agency/produit/produit-test/
the original image is 673×963

and I tried several settings but without any success. For the moment I put auto for zoom box width and height and 500 for the image size.

Please could you help me to resolve this problem
thank you very much
Florence
