Hi @omi053,
To clarify, are you saying that you've opened 5 packs total, and received two legendary items and a green (iconic) item?
Your event item tracker is showing 5 items collected, but you're not seeing 5 legendary/iconic items, is that the issue?
Edit: Fortunately after taking a look, you don't appear to be missing anything. All your packs were opened and the items received. You've certainly received the guaranteed legendary as well as a couple more.
Of the 5 event packs, you received:
3 Legendary items - Bocek, 301, and Nemesis skins
6 Epic items - Charge Rifle skin, shared character frame, Mad Maggie skin, sticker pack, Bocek skin, holospray
6 Rare items - Volt, Charge Rifle skins, Conduit quip, Conduit skin, Caustic pose, Crypto frame
This for a total of 15 items, which is 5 packs.
This matches the rest of the cases here, where the packs are being opened in the background if that interface is left.
That is certainly not ideal, but you have not missed out on any of the items or packs.
