void's in my ply

ive cut out my profile and have found some voids in the top of the 3/4 ply one is 2" deep but 1/2" wide another is 2" wide and 1/2" deep
do I just fill these with glue or something else
its because I used seconds ply and I'm on a tight budget. They were $10 each as opposed to $70 at Bunnings hardware (our version of home depot?)
