Mirrors are going to be impossible to process. As noted in our Data Collection guidelines that are agreed to at the time of upload:
-------------------------------------
Avoid Sun Glare and Highly Reflective Surfaces
You shouldn't stare into the sun and neither should your camera.
Even the best cameras have a limited range of brightness they can capture. When an area is too bright, it washes out all of the detail and makes that area lack the detail needed to reconstruct the scene. The roofs of large buildings and wet pavement will often be too reflective to capture properly. This can be dealt with by mapping at a different time of day in which the sun will not be reflected directly into the camera.
----------------------------------------
I would say mirrors are pretty reflective and are bound to cause issues.
Your overlap is also far too low especially since you are using a Mavic Pro which usually requires more overlap to get successful results, not less.
There were also a number of images that included the sky and the horizon in the data set. This too is warned against in the Data Collection guidelines.
I doubt you will ever get good results using photogrammetry when looking at a field of mirrors.
