Very minor bug: card incorrectly displayed as "missing"

[Lohoris]

This is very minor, I'm reporting it anyway but feel free to ignore!

---

I have 3x Beskir Shieldmate in my collection.

In this deck when I added 3 to the deck or 3 to the sideboard I think it worked fine.

However now that I have 2 in the deck and 1 in the sideboard, the "missing cards" complains that I'm missing the sideboard one.

If I go to the magnifying glass it says that I'm using it in another deck too, but that deck is not marked as active, so it shouldn't count.

Same problem in this deck: https://deckstats.net/decks/38436/2475374-gates-to-victory#show__stats

I have exactly 4 Maze's End and 4 Gateway Plaza in my collection.

For both of those cards, the deck has 3 in deck and 1 in sideboard.

The sideboard ones are reported as missing, saying that "I have 3 of them in other decks".
