Feels Like Heaven by Katy Dunn (park scene with Alex and Clio)
This episode is titled "The mysterious singer" in France.
After watching Nobody's music video I Am Nobody, Diana says "3 millions of views in only 4 days" while on her computer screen we can see "Nobody phenomenon, 3,000,000 of likes in 3 days". Later, on episode 37 recap, Diana repeats the same sentence whereas on her computer we can see "The Nobody phenomenon reaches 3,000,000 of views in 4 days".
In some countries, the screen was blurred to hide the Italian text in the episode but not in the recap, even the goof wasn't solved.
