Images not scalling in HERO module at small screen devices

sp22

Hello,
I create module using JA ACM Hero and insterted it in my home page. There is a problem when I open this page on mobile or tablet - it seems to not be responsive. I used Hero - Style 1. Background image not scale itself and my added picture in Title neither. Texts are responsive (and button too).
There is another Hero module at that page - down - based on Demo content - and there background image is responsive as it should be.
How can i make my background and other images in Hero module make responsive? I cant see any options in module configuration.

Hi
The Image loads as background image so its property is different. It loads behind the text to fill complete background area behind the text. If its set to 100% there will not too much blank space and it does not fit complete area.
here is example code you can set via custom.css to force the background image size as 100%

@media(max-width:768px){#section-530 {background-size:100%!important; }}

It will make it like this http://prntscr.com/z1gl37 as the image can not fit the height.
