I hadn't noticed this before. I can't see anywhere that there may be cracks or any other place for air entry.

Waves in roof material

You might want to add a long strip of Eternbond tape at the transition from the front cap to the roof covering the Lap Sealant already there. The waves are prevalent on many roofs that I have seen. The Eternabond will add a second barrier to the already existing lap sealant. The current sealant looks fine BTW.2021 Solitude S-2930 RL

I am going to say yours is happening because the adhesive didn't grab the TPO membrane in those areas. Different coefficients of expansion and contraction between the TPO membrane and liquid Alpha sealant are causing the waves. It probably wouldn't hurt to put some more Alpha sealant or Eternabond tape on those areas that are puckering up. They probably aren't leaking but better to be safe than sorry when it comes to water intrusion.Mike & Lisa
