With second toolbar in use, I often find various items that are supposed to be in tool bar to be in inventory at smaller amounts. After some testing, I found out that this always happens for that toolbar that isn't currently active when you get items. They go to inventory without checking if they should go to the currently hidden toolbar. This applies to all kinds of item getting (crafting, picking up, mining etc).
Edit: You can also override filters... If you select an item from active toolbar and then switch to another toolbar and select another item from it. Then hit unselect items with q. Now the first item is placed into place of second item that was filtered not to accept the second item.
