Heirloom Pack Question

[Uzzy321]

Hi all, so today I received a bloodhound heirloom Pack whilst opening some apex packs. However i already had purchased the heirloom from the iron crown event.

I want to know if this had affected my chances of getting the wraith heirloom Pack out of the 1/500 pool.

And if it does affect my chances of this, what can I do, given the promise of no duplicate item packs.
