How can I delete completion of a merit badge that was accidentaly completed

I have a scout that was accidentally marked as completed for Small Boat Sailing by the MBC. (The MBC did a mass approval for the class, but didn’t remove the people not in the class). Because it is marked as Counselor Approved, I cannot seem to delete the completion. Is there any way around this?

@JasonKracht the MBC would need to clear out their own mistake. Or you would need to delete that MBC and assign a different MBC.
