Impulse theme: Image order is jumbled after updating theme

Hello everyone,

Since I updated the impulse theme my product image order is jumbled randomly it seems per product page.

The image order is basically random and doesnt follow the order of the product page in the backend. I am certain its because of the theme update because any version prior to the update works normal and as intended.

How can I find the error of this or how can I fix this? I just want the first image to be displayed first when opening a page.

This is the page ozado.de

Help is much appreciated.

Peter
