GCPs and processing point cloud

We are processing a flight with GCPs and we have one area of our flight that is giving us an error or different in the GCPs elevations and the computed elevations of more than 5 feet and another of 13 plus feet. We have tried everything to correct this and cant seem to get it to work. We are up against a hard deadline and cant afford to lose this client or contract.


This is what one GCPs are doing, how do I get it it recognize the elevation on the GCP, not the computed?
