Removing Hero from page in 2017 Theme

We have been referred to this Theme forum for Help by Gareth in a previous request for Help in another Help Forum. He stated that this might be related to our theme, and not to any plug-in.

I have been trying to remove the hero from the blog page of our website. The blog page is simply a subdomain of our main website, eacjci.org.

The primary problem is that the hero appears in the desktop version, but not in the mobile app version. In the mobile version, we can see the logo of our business just under the title of the blog page, even though it is not showing up that way in the desktop version.

I have followed the instructions at https://www.ads-software.com/support/topic/how-to-remove-the-hero-slider-from-the-main-page/ However, when I get to the main page in the Customizer, and look for the Hero there, it is not to be found. Our logo seems to be appearing on our desktop version as a hero with the slider function, while I am actually viewing it in desktop version, even though our logo is showing up in the mobile app version without the slider function, even though I am working with it in desktop.

When I follow the instructions at the hyperlink above, and go to “Appearance” on the dashboard, and then to “Customize” in the drop-down box to the right of the dashboard, I do not see any “Show title”, “Show subtitle” and “Show buttons” checkboxes, that I should uncheck, as explained in the instructions from the “Link to the page [I] need help with” in the box shown with this request for Help.
The instructions from the hyperlink for “How to remove the hero slider from the main page” say that I should be seeing “Show title”, “Show subtitle” and “Show buttons” checkboxes, that I should uncheck them and then set top and bottom content spacing parameters to 0.

However, as you can probably see from the “Link to the page [I] need help with,” I do not see where those are on that dashboard screen.

Where can you suggest I go from here to accomplish what we are trying to do?
Your assistance will be very much appreciated. Thank you.
