Anyone ever experienced this with 'Suspicious Trenchcoat'

In stage 5 my Violet triggered her suspicious trenchcoat and at the end of the round I won when the copies were dancing one of them remained on the board when it reset for the next round, so I had 1 normal Violet and 1 dancing Violet clone on my board

When the next round actually started the dancing Violet danced over to the enemy team and instantly regained all her HP and became an exact copy of my normal Violet (the suspicious trenchcoat didn't trigger on the clone however)

In the same game 1 stage later I played a Vi and Trait: Sisters appeared in my traits list despite me never having picked or even been offered it, I didn't have a Jinx to see if it'd actually work though unfortunately
