Major issue with selling stacked items

I tried listing Incubators for sale, being unsure how the stacks worked I listed them 1 at a time for 4 chaos each.

However when using ctrl + leftclick to list the item, while I got a popup to choose the price, the item was instead added to the stack of identical items already listed for 4c.

So when listing 8 incubators one at a time for 4c each, they instead got added as a stack of 8 incubators for a combined price of 4c.

I tested with 3 different ilvls of incubators and they made 3 different stacks, but kept adding additional items to the appropriate item lvl stack without increasing price.

Luckily this only ended up costing me around 60 chaos, but if I hadn't noticed the interaction I would have lost closer to 500.

A small added issue:

Since I didn't notice this instantly the initial item added was locked, and adding new items to the stack did not unlock it. So even if people notice this bugged interaction they are unable to fix it, since the newly added items are locked in your shop.
