First solo vfr objectives not indicated landing at wrong location not what was expected

Good day,

exactly the same problem ! I’ve done the flight with the good altitudes, speeds, I’ve flown over the waypoints, used the chronometer… and the same issue: “you have landed on the wrong place !”
I watched videos on Youtube where the guys did the flight without any respect of altitudes, speeds or landing runway, and the flight was checked !!!

Quite strange.
