FIXED product thumbnails uncropped?

UPDATE
I found this code and that fixed it:

add_filter( 'avf_wc_before_shop_loop_item_title_img_size', 'avf_wc_before_shop_loop_item_title_img_size_mod', 10, 1 );
function avf_wc_before_shop_loop_item_title_img_size_mod( $thumbnail_size ) {
    return 'woocommerce_thumbnail';
}

I am building a shop with woocommerce and I have selected in the customizer to have the product thumbnails be uncropped, but they are defaulting to 1:1. Have tried all combinations. I have setup another page to be the shop page, using the Shop Single 450×999 image size, which works OK, but all the related products are still 1:1 ratio. Can you see what’s blocking the upcropped setting?
thanks
Nancy
