Infidel (Men of Iron) Modules - Can't flip Crusader seizures

The Crusader seizure tokens cannot be unmasked/flipped by the Crusader player. They can be interacted with if your playing as Solitaire.

This problem exists in all three of the Infidel modules. I am currently using Vassal 3.5.3.

Beyond retiring and coming in as solitaire, any thoughts on how to fix this?
