@tomxygen Thanks for opening this issue! I added this issue in the main issue about the Single Product Template. I can confirm that this is different respect classic WC Core template:

Classic Template	Blockified Template

I noticed the different styles for the Products block as well:

Classic Template	Blockified Template
