If your castle VUK is already adjusted to the limits of its "trajectory", you can use this simple fix to make further adjustments.
A small piece of weatherstripping on the edge of the scoop can slow the ball just enough to change is momentum to avoid your problem.
Normally, this problem is more common when games have been recently rebuilt due to the clean coil sleeve and coil strength.
However, I would also check the long ball rail on the left orbit.
These can get bent over time (ball strikes), and actually can be adjusted with the mounting screws to reposition the piece to angle the ball directly back to the left flipper.
