Issues with Currency and stacks

For some reason sometimes PoE 2 recognises a whole stack and a single as the same thing.
I tried with the shop and there is definitely somethign wrong.
Try grabbing a stack of Augmentation orbs, split one off, and then try selling the stack of augmentation orbs and the single orb separately.
(Don't worry you can just use buyback to get them back, so it is easy testing....)
Does the stack and the single orb both only sell for 30 gold as though they are the same size?
Mine does.....
If I am not the only one then there is definitely a bug of some sort there...
