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" in Italian. 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 Hungary, Czech Republic, Bulgaria, Romania and Poland, the screen was blurred to hide the Italian text in the episode but not in the recap, even the goof wasn't solved.
The Dutch dub solved it by saying "3 days" instead.
In France, the screen shows "Phenomenon Nobody 3.000.000 likes in 4 days" written in English. Here there is the mistake of separating numbers with a dot instead of a comma.
