Question about big rear glass install

[Metalaroundstone]

I just installed the rear glass in my truck using a precission seal. Unfortuneately, when I was done I noticed that the seal puckers around the two bottom curves of the glass. It's okay on the two top corners (which are more gradual). Is this normal? I can't remember whether or not the old seal puckered. How can be this be corrected?

Thanks
