Main Image Width setting not resizing images in WooCommerce Customizer

I am getting the same image size when I click on a product, despite changing the Main Image Width in the Customizer for WooCommerce Product Images. The Thumbnail Width resizing is not getting results with Customizer either. I was originally using 500 width px images and changed them out for 300 width images, with the same result. There is also an undesirable slice of text showing up to the right of the enlarged image. Help on this is greatly appreciated!!

I have carefully completed the pre-topic checklist, searched this forum the internet for solutions already.
