Having different images for mobile and desktop in the section "Newsletter" on PRESTIGE theme.

Hi there. 

Been trying to solve this for 6h, but can't get it to work on my specific theme by using instructions made for other themes. I been able to customize the editor to make the sections for uploading different images depending on device appear, but there's something that goes wrong and I get two images on top on each other as an end result. I have no coding skills, I just like to fix things myself by using the great tutorials experts provide in this forum, but this time I feel beaten by my own inexprience;) 

If anyone can help me fix this, what I assume is pretty easy when you know how to do it, I would very much appreciate it. Of course I would gladly pay for the service!

Thank you so much,
