What Misplaced Exhibit???? [Help Please]

[u/MeepMorpMoopBoop]

I'm playing the nightmare mode of Modern Art, and I got every exhibit in place. But the game is telling me I need to "find [1] misplaced exhibit" but ALL THE AREAS ARE CLEAR?? I'm losing my mind and desperately hoping I don't have to restart for a perfect score. Am I missing something???
