Hi Jerome,
when a customer creates a wishlist thats fine. But if he wants to delete items from the wishlist he cant. As you see in the attacknet, the table shows the header "delete", but under that, there is no option to actually select the products in the wishlist and remove them from it.
Also, I have observed, that when you add the wishlist to the cart to now buy the items, the wishlist is not emptied but remains the same with again the items not being able to delete from that list.
Hope that makes it clearer.
Regards
