This is going to sound stupid, but don't forget to activate bed levelling after performing the leveling measurements. Maybe this is a stupid idea but I put M29 L1 and M29 A at the start of my gcode to load the ubl slot 1 mesh and activate it. Before getting ubl I used M420 S.
I spent way too much time frustrated by bad prints before I learned that leveling wasn't active.
My two cents: don't look at anything inside that car at all. Listen to the engine to know when to shift, go a speed that feels comfortable and is a bit slower than other cars. Forgive yourself when the engine stalls or you drive in the 'wrong' gear for a bit. If you got behind the wheel and didn't hit anything, you're won driving.
That ain't right 😹
Maybe try contacting klipper people https://github.com/Klipper3d/klipper/blob/master/docs/Contact.md
Or file an issue if you think it's a bug.
