It's fine for me (displaying Peni on the Shield Training screen).
Maybe the game just didn't download something for you. Did you try force closing and re-opening the game?

For me it has Silver Samurai as the preview picture and Mr Negative as the background image once you go in to it. It had Peni as the preview previously, though it has had Mr. Negative on the background for a little while. I did close and restart, no change.
All Asian ppl don't look alike 🤦♂️🤣 . Plus penni artwork does not make her look Japanese... unlike her support picture...
