Bugs in the Nosebleed Grind challenge

I'm experiencing a lot of bugs in the new Nosebleed Grind challenge, some of them may be bugs and some of them may just be really difficult things. But the main problem is transitioning off the rail. The objective to do the rail transfer sometimes doesn't register, sometimes when holding the left stick to the right, I fall off the left side of the rail when trying to do the rail transfer. I've somewhat figured out how to slow down enough after that, by simply ollie'ing and holding down on the left stick. Then when I start grinding in the other direction it gets difficult to stay on the rail, and at the part where you need to go off the rail down onto the ground at the stadium, I have a lot of trouble landing well, sometimes I fall off the right side of the rail while holding the left stick to the right. I think there was a time (might be my most recent attempt) where I got off the rail to the left clean enough, but slammed because I think I was still holding the left stick in a direction which made me rotate and land 90 degrees off the rotation I should have landed in. I believe I had already actually completed the challenge one time, but the rail transfer objective hadn't registered or something, but either way, it felt correct but didn't count as getting them all done. I have a clip of me getting right to the end of the challenge and slamming as I tried to make it over the rail to the last bearing :( Overall the main problem seems to be the difficulty transitioning out of a grind. When holding a direction on the left stick, I see the skater attempt to get out of the grind, but he is immediately put back into the grind and struggles to actually get out of the grind properly in time or before slamming.

I'm going to try it another time because I was getting a bit annoyed at it, I got the Grind Distance, Nose Grinds or 5-0 Grinds, and Rail transfer at the Spot objectives done which is something so I'll do some other things for a bit. There's loads of other stuff I can do and enjoy in the new season :]

All this aside, I am really enjoying the new season (I know this isn't the correct area for feedback but I felt I needed to say something positive to show I do still love the game! :D )
