I promise you it's not glitched. You're landing so far along the first roof, it's causing you to lose all your momentum. If you bounce then that just means you bailed, the animation might look like a glitch but it's not.
I've also attached a video since I wanted to see if you're right as I've also suffered from many bugs this season, but I first tried it. You can see from my video if you land at the very top then you can easily overshoot it like I almost did. Don't just spread eagle all the time during these types of challenges. Alternate between bumper diving, torpedos, just falling and holding forward etc. as needed, it'll help a lot with any challenge that requires flying. Changing your FOV might genuinely help too, it's so distorted it's no wonder you're missing the landings .
Good luck!
