Why do images display incorrectly on my Debutify 3.0.2 theme?

[david256]

I'm using Debutify 3.0.2 as a theme, 

Can you please help me solve these problems?

1st problem is that the order of the images on my website is not like the way I arranged them on Shopify 

2nd problem, when you open a product page, it shows you the images of the variants first 

3rd problem, also related, the size of the images shrinks, so we can't see the whole image

this is the link to an unpublished theme’s preview, I used random products to show you, but it's the same thing on my actual store
