Creating new pages for metafields on product pages disabling add to cart & buy now button

I have many existing pages for Size Charts and product details. Those are all working fine.

But suddenly now, when I am creating new pages or updating existing ones and then using them as metafields on some product pages, they are disabling the add to cart & buy now buttons on those product pages.

Also, everything looks perfectly fine in the live theme editor (where we customise the live theme, make changes), but on the actual website, it ain’t working.

What could be the reason? Please help

Hi Hangookd - could you share the store URL where this is happening?
