Hello,
If you disable this option https://prnt.sc/13la0p6 then product title appears on the page and use the h1 https://gyazo.com/ad0cfdc1e161ea75d7d9a28a14fee07f
So, don’t understand your question. Where do you want to show the h1 title on the page? provide screenshot of where that title should be.
Regards
