Cards in other sets with the latest being from Time Spiral

I have been adding cards and it seems that cards reprinted in Time Spiral only get that option when adding from the dropdown list.

Say a card has been printed in 2-3 sets and then was reprinted in Time Spiral, but not after that, the only option you get for set is Time Spiral. I don't know why Time Spiral nulls out the others, but after adding some 1000 cards, I hope there is a way to remedy this. For now, I have added the cards, let the option be Time Spiral and then edited after. The dropdown list have the other sets after cards have been included, not before.

Hope this can be fixed easily. I love this site and have included some 30 000 cards now in my collection/library
