This isn't a bug, but it did cause a bit of confusion at first. In the trading opportunities, there are now sometimes blank rows which nevertheless have quantities, prices, and editions. I believe this is occurs because it omits the name for consecutive duplicate card names where one party of the trade has indicated that they have editions from multiple sets for trade.

Now that I know what (I think) is going on it's ok, but I think there might be a better way of displaying such information. Similar to the inventory screens, perhaps a blue/white row offset pattern where the same card names are displayed but in a contiguous block of the same color row?
