try to change woocommerce_thumbnail size / shop_catalog to portrait format

hi support team

I would like to change athttps://www.laden70.ch/shop/ the image size woocommerce_thumbnail size / shop_catalog from 450/450 to 450/800.
i load the simple size plugin and change the value:

woocommerce_thumbnail size Maximum width
450
Maximum height
800
Public name
woocommerce_thumbnail
Cropping
Yes
Show in post insertion ? Delete

and

shop_catalog size Maximum width
450
Maximum height
800
Public name
shop_catalog
Cropping
Yes
Show in post insertion ? Delete

alos i add in funktions.php of the child theme:

add_image_size( ‘woocommerce_thumbnail’, ‘450’, ‘800’, true );
add_image_size( ‘shop_catalog’, ‘450’, ‘800’, true );

but in the simple impage size plugin in the Thumbnail regeneration section are stil the old value.

What did i wrong?

All the best,
Pascal
