tearing in scenes

its two different shoots done on different days.

the shoot without the tearing is on a sunny day 6 months ago and was done using a Mavic 2 Pro and a Phantom 2 RTK (two different drones) on a old version of RC. It was a total of 5 shoots (oblique, aerial etc) which we fed into RC 

This older scene processed perfectly without needing any control points at all despite heavy shadows and over-bright conditions.

the shoot with the tearing was done a few weeks ago on a cloudy day with no shadows and perfect conditions. It was a total of 5 shoots as well but all with a Mavic 2 pro - we thought it would be better for processing to have one camera

With the current version of the software and the new shoot we can only get the different shoots to align using many CP’s and even with perfect CP offsets we now get the heavy tearing.
