Reclaim questions

I have spent dayyssss moving my stuff from a regular world to my sovereign. Stacks of stuff 100 at a time is …tedious.
But, what I don’t get is, why can I move 16 torches in one click, not not black atlases? Or weapons/tools? Augments?

Seems to be sorted by type I think. So you can have stacks of the exact same thing but not stacks of slightly different things…? Example: AOE mining hammer with loot magnet won’t stack with AOE mining hammer with glow instead of loot magnet
