How do the new legendary collections work?

[Deihnyx.6318]

Maybe I'm missing something?

Each Tier 1 Legendary weapon now has a collection that seems to contain all the needed materials.

Without really trying earlier I noticed it was possible to right click "Add to Collection" on a stack of Ectoplasms... which updated a whole series of these legendary collections.
The Ectoplasms become account bound.... except I could still put them in the Bank, and then remove them again and poof, they wouldn't be account bound anymore.
Same for the Piles of Crystalline dust (affects Eternity)

Gift of Battle and other Gifts laying around in bank though? They don't work in completing these collections.
Has anyone experienced something similar or understand what it's meant to do?

 

Thanks

it seems to just be a tracking thing, gives no AP or rewards
