Primal equipement cannot be sold on the GE

Hello Scapers,

After finishing my primal set +5 for the masterwork sword achievement, I wanted to sell it on the GE.

However, for all armour pieces apart from the helm, "you cannot but or sell this item on the Grand Exchange"...

looking for buying it, it seems that only the broken version is tradable, except for the helm .

broken primal tradable

broken and repairedprimal tradable

Is it intended this way or is it a thing to be patch after launch?
