Yeah, you are right!
That one front section should be redone.
Because their roofers need to learn to NOT install shingles over wrinkled underlayment.
Let me guess, that was the last section done
Early in the morning while felt underlayment was still wrinkled from the nightly/ morning Dew.
And the roofers didnt know to slice through the wrinkles thinking they would hurt the roof.
Now they get to do it over again.
Slice through the wrinkle with your knife or wait untill the sun dries it out flat
Or tarp the roof over night even if no chance of rain
That way, underlayment is flat and unwrinkled in the morning.
yes, my fellow roofers, i know synthetic underlayment never has this particular problem.
