What´s wrong ???

Your overlap reports show 50-60% overlap which is well below what we generally recommend. As noted in our Data Collection guidelines that are agreed to at the time of upload, we recommend at least 75% overlap. 

Also, you have a lot of large bodies of water in there that have some large sun refections. This too is warned against in our Data Collection guidelines. 

The Mavic Pro has a very slow rolling shutter that requires more overlap, not less. If you are planning on doing this professionally I would highly recommend using a larger aircraft with a higher quality camera. The Mavic 2 Pro has a great camera but the original Mavic needs an extra bit of overlap to overcome is small optics.
