[ContextCapture] Error of Aerotriangulation submitting process

In our nearest project, we took roughly 700 photos to generate a riverside area. Including: ~160 vertical photos and ~550 oblique photos. At the first time we started this project, there were 2 error occured in aerotriangulation submitting process : 

- All of Vertical photos cannot be used for reconstruction. (image no.1)

- At 3D view : appeared another model of that area (same with normal ones but have different scale) and it located in the air .(image no.2; 3)

However, after that we created another project, used the same photos and it was ok. 

Althougth this area is generated completely, but I still want to know the reason why those error occured (guarantee for next big areas)

Thank you.
