You have improved your menus since yesterday. There were too many menu’s I thought??
Your side menu on the left should include all of your pages except for the ones you exclude by inserting page ID and comma in the widgets section.
The only way I know how to take the menu items off the blk and white horizontal menu is by going to appearance > menus
on your right hand side are your pages that appear in this menu. They will go there automatically when you create a new page and click ‘publish’, if you wanted them to go there or not. Remove them by going to the grey coloured box with the page name inside it. Click the down arrow on the right and click ‘remove’. This does not DELETE you page, it just removes it from THAT menu. I hope this works for you?
