Hello,
XStore AMP (Accelerated Mobile Pages) is a plugin released to help improve the mobile browsing experience. It is created to render the page faster by only loading the text, media, simple styles without scripts and many styles that Elementor or WPBakery plugin generate, so it supports the WooCommerce page (because pages come with simple styles and texts) and does not support pages created Elementor/WPBakery.
1) When the AMP version is enabled your header looks in this way https://prnt.sc/1icov0r
What do you want to change there?
2) If you don’t want to show that switcher you can disable that https://prnt.sc/1icp7of
