Alt Arts not working

I have been trying to update some of my decks with the alt arts that I own but I cant seem to select them like I used to.

Hello! Are you clicking the alt arts button and then clicking a card in the deckbuilder? For example, open deckbuilder, enable alt arts, click Abbadomon Core to see alt art version.

FYI, our old deckbuilder had no support for alt arts. 

Yes, while editing another deck I saw that some of the alt arts are missing and that was the problem, would this be an easy fix? for example Shu-Chong Wong had no alt arts present in the deck builder. While Terriermon had some but not all of them.
Thanks for the quick reply!

Ah I get you now, we're missing some alt arts altogether. It's not a quick fix but it's something I'll investigate! I'm handling alt arts in a completely new (and tbh better) way than previously but there's still some work to be done. I'll keep at it!

Amazing work as always, Happy Holidays!
