Check Shop page now. Theme Options > WooCommerce (Shop) > Shop > Products style > Show Excerpt In Content Product > Off.
It is because your excerpt contains tags, and when a part of the excerpt is taken to show on the Shop page, some unclosed tags cause the problem. Keep the option disabled or edit the description of products. You can add a few words in the Short description area, without tags, then content will be displayed just fine.
Site Width you can change via Theme Options > General.
could you tell me why ( or fix ) the main page, when you initially load the page, it has to stretch to cover the complet page, is there a way for the homepage to be full page at the bigginning? It’s related to the speed of the scripts loading. Elementor and our theme use scripts to make full-width row, and apply styles, so it does not display like full width till the necessary scripts loaded. You can enable site preloader (Theme Options > General) to hide that effect or try to speed up the scripts loading using cache plugin, improve server speed settings.
