Quoted from LTG:
Standard ball trough used on Williams games, Remakes, JJP games, etc.
Be sure your playfield is level left to right. Hasn't been an issue on other games.
I have 4 games on the same floor, none of them have this issue (and all my feet on wonka are threaded all the way in)
The design is the same, but something is off. My Williams congo has 24mm of gap from metal to playfield, JJP has 27mm of gap from metal to playfield. This means the pitch on the JJP trough is more shallow, hence why the balls sometimes hang up.

ltg can you please contact someone in engineering to verify if something changed? or someone with another JJP game in this thread with a pair of calipers can verify this gap?
In the meantime, I 3d printed a chunk to fix this issue (I hope temporarily)
