Hi,
As you can see, the warning is in a view override for the view "product / listing_table".
So you need to edit that view override in order to fix the issue.
But because it is an override and not the official HikaShop content, we can't fix the issue because we do not have the same content in our side.

By the way, do not send me private message, use the "contact us" form instead.
