Cannot access superclass

Hello...I'm an instructor of a college course and one of my students just sent me the following RapidMiner error:

class.com.rapidminer.belt.itemsetcolumn cannot access it superclass.com.rapidminer.belt.simplefreecolumn

Can anyone point me in a direction to solve this issue?

Thank you!

    can you maybe the process where this occurs? This look like a clear bug to me.

    Yes, I attempted to add that but was unsuccessful.

    Retrieve -> Select Attributes -> Numerical to Binominal -> FP-Growth

    The process runs at each step up to FP-Growth and then the error occurs.

    Thank you!
