Something weird in my Broker : EverQuest 2 Premium Discussions

Ok, so first, here's some background info. I put up about 8 stacks of creamed robust coffee up for sale on my offline selling this morning. So I get on today, go into my house, and find that alot of my coffee has been bought, but not all of it. I open up my vault window and see that there are about 4 stacks left, but they are not full stacks. 1 has about 6 coffess left, another 16, and another 3. I then check the broker just to see if I can increase my price a little, and lo and behold, I see 5 full stacks of coffee being sold by my toon. I then search the broker for my toon by name, and still see all 5 stacks of coffee full. I didn't understand what was going on, so unlisted the items, and listed them again immediately, and my stacks on the broker went to their appropriate count. Anyone have some input on this?
