Files not generated during 1. Initial Processing for merged project

I am wondering why these files are not being generated during 1. Initial Processing and how to correct this.

 

_measured_estimated_gcps_position.txt

_wkt.prj

_tp_pix4d.txt

_pix4d_calibrated_internal_camera_parameters.cam

_calibrated_camera_parameters.txt

Let me know if it is the case for you or not.
