Dimir Signet from Zendikar Rising Commander decks is showing the silver Uncommon logo on deckbox, but the card itself is definitely a Common.
Mind Stone from Zendikar Rising Commander decks is showing the black Common logo on deckbox, but the card itself is definitely an Uncommon.

Three tokens from Commander 2020 seem to be wrong:

  • Angel // Elemental -- The elemental side shows C20 T003 (colourless? 4/4 with flying), but should be C20 T010 (red 3/1).

  • Elemental // Kraken -- Again, the elemental side shows C20 T003 (colourless? 4/4 with flying), but should be C20 T010 (red 3/1).

  • Spirit // Insect -- The insect side shows C20 T018 (blue/red 1/1 with flying and haste), but should be C20 T013 (green 1/1 with flying and deathtouch).

The wrongly-shown faces on all of these cards definitely appear elsewhere in C20, but I'm not sure whether the incorrect dual-sided combinations legitimately exist somewhere. It seems like Deckbox might just need scans of C20 T010 (Elemental) and C20 T013 (Insect) to replace the incorrect images.
