Variation Problem no working and conflict with theme zoom feature

Dear Woocommerce Author,

Currently I am facing conflict problem between woocommerce 3.0.1 variation and theme zoom conflict. Here is the sample of the product http://www.shopbuzz.com.my/product/iphone-66p77p-soft-back-casing/
When I select an option of the product then the featured image of that option was no showing. Currently the theme that I using has 4 zoom style, when using default zoom the variation working but when using other 3 zoom style the variation no working.
Then I got contact to theme author they mentioned not their theme problem is because of woocommerce 3.0.1. Before update it working well.

Thank You
