I had that same hood issue several times and I fixed it by rotating the hood where it bolts to the hinges. Basically you open your hood, loosen the bolts holding it on the hinge and try to rotate it away from the car, pushing the nose towards the radiator and pulling the top away from the car. You wind up having one hole at the bottom of its adjustment and one at the top. Be gentle and don’t bend the hood, helps to have many hands. Might not work on all cases but worked well enough For me on two different cars, definitely worth a try.
I can’t remember what forum post I got the advice from. Only issue I’ve noticed using this method is you have to close the hood a bit to use the prop rod.
edit:
oops I mean what sheen said, no idea why it works different than the push-down technique
