Market Discussions

I listed some Caldari Ballistic Control Systems on the market today. The first thing I did was to find them all in contracts. I sorted them by price, low price to high, then listed them at 1 mil less than the lowest one. My contract didn't show up as cheapest when I did a second search listed low price to high. So I then changed the price range for 1 mil lower than the lowest price showing and it still didn't show mine.... There were then a lot more listed lower than what mine was for. However, these still weren't the cheapest, after fiddling with numbers, it finally shows that the cheapest are right around 90 mil. So when I cleared out the numbers again, and just searched for cheapest to most expensive, it was still showing the 124 mil as the cheapest when 90 mil was the actual cheapest. What gives?!
