These examples are completely off the top of my head, but the bug is still there.

When importing cards from a specific edition, I'll set the default set to that edition. So say I set it to 7th edition, and I have three counterspell(s), I type in counterspell then hit '+' twice. The second and third counterspell that's added won't be the proper edition even though I have the default set. (just an example, it may not be that way with this specific card, but it is with a majority of cards)

Yep, we still have a bug with this, but it's going to be fixed for next release. Thank you for reporting.
