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

As First time training session solo vfr,objectives(waypoints) not shown.when arriving at sedona instructor says mm you weren’t supposed to land there. Any help please.

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.
