Can't put South Vern dungeon rewards in Roster Storage

I just finished my first weekly dungeon in South Vern and I was really surprised you can’t put the chest (I took the leapstones’ one) in my Roster storage. We could do it with Anguished Isle’s rewards but now we can’t?
It is a Roster limited reward and we have to guess it is not possible to transfer it to our alts? How dumb is it? Please change that or at least tell in the shop I can’t transfer it to my alt…

The same happened to me, because usually every honing material inside a chest is roster bound. But those rewards are not, despite being a roster wide purchase.
