When adding the Duel Decks: Elves vs. Inventors (https://deckbox.org/editions/472-duel-decks-elves-vs-inventors) to my inventory, I noticed that the symbol used for the uncommon cards was actually the common symbol (white vs silver) (for example Treetop Village https://deckbox.org/mtg/Treetop%20Village?printing=38353&lang=us). Rare and mythic rares were correct.
I tested with filters and the cards do seem to be correctly tagged as uncommon, the symbol is just incorrect.

Thanks!
