Hello TheOne,
Thank you for choosing XStore as your WooCommerce WordPress theme.
Please go to Theme Options > WooCommerce (Shop) > Shop > Products style > Show Excerpt In Content Product > Off.
It is because your excerpt contains tags https://prnt.sc/g_zH4_5I7mSM , 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 the content will be displayed just fine.
We hope this information is helpful.
Kind Regards,
8theme team
