As the title says the action buttons are now showing at the right spot... here is the picture of how it looks on the page. Does anybody knows how to fix this ? Thank you.
That's most likely caused by some CSS or JS from a third party plugin or your theme. Try switching everything except WooCommerce and FPD off and using one of the basic themes like twenty seventeen. If it works then it's a conflict with one of these plugins/ theme - you can identify which by switching them back on one by one. Once you have it identified you might want to contact it's support for a fix.
