Roof ripples/bubbles at seams

[nano]

I went up on the roof of our 2013 Cougar 333MKS for the first time this year, and found some ripples/bubbles at 3 seams in the roof. Have any of you experienced anything like this? In some spots I can feel the sealer right underneath, but some spots have air under them. I have an email in to the dealer and to Keystone, and my gut tells me this isn't normal/right. Our 1 year warranty expired in May, and I hope that doesn't cause a problem for us.
