Woocommerce product images

Hello

Sydney theme is ignoring the woocommerce Main Image Width.

Appearance > customise > WooCommerce > Product image settings.

I changed it from 600 to 300 but the image size stays massive no matter what I do.

Here is the support ticket I opened with woocommerce:

Please can someone advise me how to solve this.

Thank you kindly.
