In the activities history section (https://www.geoguessr.com/en/me/activities) the english "You've played a competitive Moving Duels [game]" should be translated to "Vous avez joué une partie compétitive Moving Duels." and not "Vous a joué une competitive Moving Duels Jeu."
The conjugation and the meaning of the sentence is wrong.
A game = "une partie" in this context.
"Vous a" should be "Vous avez"
The end of the sentence is flipped.
