Layout & Menu Relationships

Highend Theme:

Using the demo theme to design web site:
– I am trying to edit the store screens to allow the customer to select the products from 3 different menu options where the primary store uses a shop-layout to show only items from the selected store at the top level for that individual shop on the menu.

Editing Layouts:
I am confused by the theme’s usage of the layouts where some are using the edited logo and others are not?
The same thing on those layouts where the menu and the screen header are the same as the default demo screen. Where several adopted the header and menu from the home screen others did not.
There are some of the shop screens doing the same thing as above.
Some shop screens are showing the products from the demo and others are showing the one products I added for one of the stores I added. So there are settings somewhere to change this functionality?

How do I do this?

Correct the menus to show the different stores with only that stores products.

How do I edit the layouts to conform to the home page where the menus match, and the logos are correct.

What is required to get the different shop layouts to conform to menus and headers.

Last issue:

Sliders:

I wanted to change sliders in the shop-layout screens where the slider with the sale 30% and the featured product were replaced and shows a slide for the 3 different stores. I created the slider and added it to the Shop-Layout screen and it whipped out most of the content on that screen below the slider when I previewed the layout?

Learning curve:

The approach used in this theme is very different than most WP themes where your editing tools require some study. I am not finding the answers in the forum or the documentations and certainly not in the videos. I find that I need to dig around for hours to eventually find some of the answers.
