Can't filter by Nemesis Expansion in MTG on the explore

in order to get the card im looking for, i browse the market place by extensions (really waiting for a wishlist, basically filter the market place for cards i want only) I noticed that i can select extensions like mercadian masques or Invasion but not extension like Nemesis or Planeshift. I suppose because they have less cards and that this list only fetch the bigger ones. It would be useful if it could fetch all extensions
