Back up your data and delete the app. Re-download and load up the back up data. Any time there's a weird bug, I do that to fix it. It happened to me during the Yubel event. 🔥's cards were all glitched. She was summoning the level 6 Revival Rose with no tributes. Her card descriptions were blank. She played Veil of Darkness in face-down defense mode at one point. The re-download fixed that.
