Need help with a MOT (My Summer Car)

in msc, after passing the technical inspection for the first time, a new one appears after a while. I just received such a letter with a new MOT, I tried to register for the rally, but they talked about the license plates, I got into the msc editor and started looking at the leimapapperin and carinspected parameters, carinspected was set to false and I corrected it to true, but it flies. what to do?
