Woocommerce product variation image problems

I am having problems with my site at RoodyNoody again.
A user can change the initial product image if he/she selects a size and a colour (I sell t-shirts with these as woocommerce variations). They can browse through the various colours using the woocommerce dropdown selector. No problem there. My new fancy pro image zoom plugin also allows my designs to be seen in all their detail. No problems at all until a user clicks one of the thumbnails. It shows the larger product image that you have just selected with the thumbnail but then no matter what happens you can’t then change the image using the drop down selector.A user can continue to navigate through the multitude of variation thumbnails but not the drop down selector. Nor does the zoom work either then. This problem occurred without the image zoom plugin by the way but I didn’t get around to filling in the bug report about two months ago. Just busy with other aspects of running the site.
I really do hope one of the developers can help as this unwind theme is absolutely fantastic for a free theme.

Here’s an example of one of my url’s which has this problem
