About Bentley ContextCapture

The last photo is a infrastructure from our site that we have to do a 3D image of. We used a DJI phantom 4 pro Drone to take pictures. It has a 13.2 mm sensor size and a focal length of 20 mm. We flew the drone around the building in circle, increasing the altitude as we reach one full circle each time and took around 430 pictures of the places. However everytime when we input the pictures into ContextCapture, one part of the roof will always overlapped with the original building itself in the software as seen in the 3 pictures we uploaded. The part of the roof always end up in a place/position that is out of the initial placing of the roof. Is there any solution to this problem or does anyone have any idea where we went wrong. We need solution as this is our project for our final year in our school
