Sidebars showing below main product content

Hi all.
i know there are a ton of topics out there on this issue. but is there a simple solution to fix this problem?

Theme settings are left sidebar content right sidebar.
but on a woo commerce product the sidebars move to the bottom of the page.

every other page is perfectly fine, just woo commerce products.

Im using woo canvas theme.

Thanks 🙂
