New Window Installation issues - help needed

Hi Houzz community,

We are having a contractor build a new custom home for us and he is setting windows now. The windows are Milgard Montecito windows and the have a nailing fin. We are concerned about the quality of the installation and wanted to seek your comments. It is our understanding that the fin (flange) on these windows becomes an integral part of the flashing system and that damage to the fins must be fixed as it can lead to later issues with water infiltration, rot, etc. We have about 20 cracks and many bulges in our new window flanges. Our contractor has told us that he is not concerned about this. We are looking for outside advice. I have posted a few representative photos below but can post more if that would be helpful. Your assistance would be greatly appreciated.
