laminate corners not gluing properly

Sometimes the corners of a laminated top don't adhere very well for me.I've had this issue at times in the past on small and larger projectsand on this kitchen project i'm in the middle of (which is by far the largest laminate project I've done to date). I don't know what I could be doing wrong. There's adequatecontact cement and I'm press-rolling it with plenty of pressure, but sometimes a corner or edge just doesn't stick well. Not on all corners, but maybe a third of the ones I had to do. It was no biggy to correctwith 2-part epoxy and clamps, but frustrating fussiness nonetheless.

This time I also had two ends about 24 inches across that I noticed were wanting to open up slightly. Fortunately I noticed those soon afterthe lamination process and I clamped them down with a caul. Left them overnight and there's no more issue.
The entire countertop adhered well, but just nota few corners and those two edges.

The contact cement isn't that old. A few months since I first opened itand it waskept inside the house between use. I mixed it well. The 5x12 laminate roll was taken out of the shipping box a good week ahead of installation and left rolled out to relax for several days. Eventually I did roll them back up into large rolls to stand up out of the way. The diameter was like a good 36-40". So it's not like I popped the tightly rolledlaminate out of the shipping box and slapped it onto the substrate.

It's going to be a long minute before I have another plastic laminate project, but what could I maybe do differently to avoid this adhesion issueandhaving to fuss with it?
thanks!
