Collected data does not change even though data is acquired after changing the location of the object.

I want to get the data of lidar sensor from unity. Therefore, a simulation scene was constructed as follows, and lidar data could be acquired. By the way, i want to acquire the new data by moving the position of the biggest building back a little like below picture. Even though i changed the position of the building, the obtained simulation data continues to be the same as before.

However, it is applied by changing the position of other objects( small building, car, tree etc ). It is judged that only that building ( the biggest ) does not apply.

What's the problem..?? Please help me ㅜㅜ
