Top margin missing

I don’t know wether this question is beyond your scope of support
because it is a Woocommerce issue (I think).

However, I am using Vantage that generates the page in question,
so maybe you still can help me.

When I add a product to my WC shop, WC obviously creates
a page for that product.

However, the top margin is missing and there is a sidebar that I don’t want.

Been busy to figure out tho correct these problems but cannot find where
to edit, since woocommerce doesn’t give me access to
the editing sidebar as used in page builder.

I also cannot find the “product” folder in the url above.

Is there a solution for this?

Thanks and regards,

Harold
