Aligned photos are below the stitched orthophoto?

[Cowboy]

Hey guys ending some help.  I am using a Phantom 4 pro and working on a field.  My overlap has been set at 75%, same as my phantom 3 pro.   The P3P images stick great and the aligned images are above the orthophoto like normal, but the P4P is not?  What am I doing wrong or not setting right?  Thats for any help!

Hello Cowboy,

I think that the focal length has been estimated to very small values, unless instead of sensor pixel size the size of the full sensor has been input in the Camera Calibration window.

So how would I fix that?   Where do I need to look and what should I change?  Thanks for the info!
