Frequently bought Together on Mini Cart

Hi guys,
I found a little bug using Frequently Bought Together option.
Here the step I follow.
1 I created a package with 3 product and set the discount for each one even for the primary product. The discount is the same for all the product
2 I assigned to all 3 products the same bundle
3 I try to add to cart the bundle for every 3 products

The results is always the same.
On mini cart I see 2 products with discount and one with no discount.
If I go to payment I correctly see the bundle discount price.
Please take a look the URL I attached and try the bought together functionality on mini cart.
