Info by Predrag:
Looks like there were no changes made with Upfront Builder because when theme is installed on my installation the shop page still looks good.
Seems like Upfront styles for woocommerce are not being loaded.
If you inspect product title you will see difference on this installation and clean installation.
Global CSS has couple of additional lines but that's not the cause (tested).
It looks like that shop page is not loading properly in Upfront and might be related to that.
