Hi,
Yes. This is done on purpose in the file "cart/show.php" with the code:
if($this->cart->cart_type == 'wishlist') {
$this->row->product_min_per_order = 1;
$this->row->product_max_per_order = 0;
}
That way, customers can still wish to have more products.
For example, on a wedding gift list, you might want 50 items of a product while the product can only be purchased with 10 items per order. But several persons invited to your wedding will be able to purchase the product and each one will have the 10 items limit. In the end, you will be able to reach more than 10 items purchased for you for that product but by different people.
If you try to convert a wishlist to a cart or move a product from a wishlist to a cart, it will block to the limit or refuse so it won't be possible to try to cheat by first moving the product through a wishlist (at least it shouldn't).
Anyways, if you don't want that, just remove that code in a view override and you should be set
