Why can't I hide a specific section on the homepage using code?

Hi,

I have a problem with hiding a certain section on the homepage.

I can hide an image but not another, I copied the code so I'm not sure why it is not working.

Here is the code below:

Here is the website preview:

@JKIRK 
Can you give me a screenshot of which section you want to hide on mobile?
Thank You.

@JKIRK 
Paste this code at the top of the theme.scss file.

@media only screen and (max-width: 768px) {
div#shopify-section-1637120012f9f38e56 {
    display: none !important;
}
}

@Zworthkey I have pasted the code and still no luck.

I changed the section so 1637120012f9f38e56 is now 16371246489642ab67

Thanks
