While working on a trade for a bunch of older basic lands, foil and non foil, I noticed that when I go to add them to the trade, the drop down box only shows 9 options, none of which are the cards I'm looking for. Is there a way to add a land from a particular set that I'm not seeing?

No real help to you, but this issue is also listed here.

Ah yes, sorry. Should have looked more thoroughly before posting. Thanks!
