Is the F18E 120's proxy fuses bugged? Or is it just me?

For some reason, and here’s the replay to sum both things up. I shot at an enemy mig29 (not multipathing btw) from a top down frontal aspect, and my missile COMPLETELY hit way before someone else’s did. Next, when i had an enemy (rather close in my defense) shoot a Fox-3 at me. My missile exploded yet did no damage! heres the replay:
