there is a problem with gallery under items. All variations except A2 doesn’t have set item custom image
With default option ( no selection all works) you can click on all thumbnail pictures and the main image changes well.
You can also select either of the attributes and all also works problem start with combinations …
Selecting ANY combination prevent possibility to click on thumbnails and lock image selection to current picture
Now clear selection – click on second/third or fourth thumb and then make a selection like a/3 or c/1 and hover over the big image – you will see first image enlarged not the one that you are selected before choosing attributes …
also selecting A2 ( which have a different image for combinations don’t replace the first image )
