Hello,
1. Take into consideration that there is also the mobile view of your header, hence the mobile’s logo is defined there.

2. You can define the mobile menu manually via Appearance -> Menus -> select the desired menu and in the “Display location” area activate it as mobile menu.

3. As for the footer, this is a bug in the Elementor plugin and you can read a similar issue on their Github
https://github.com/elementor/elementor/issues/16467
As a workaround, you need to click on the “Preview” button while editing your footer HTML block. And always keep the preview window opened whiled customizing and saving your HTML blocks with Elementor.
Other widgets appear correctly so if I miss something, please send me a screenshot.
Don’t hesitate to reach out if you have any more questions or concerns. We’re thankful that you took the time to share your concerns with us.
