These "null" value definitions are very common in TLA+. They also aren't compatible with TLC, the finite model checker. You have to add a definition override which reassigns the null value label to a model value, basically a meaningless singleton object value which can only be checked for equality and is only equal to itself. Since it would be annoying to manually perform this definition override in every new model, the toolbox detects definitions of this type and automatically adds a definition override for these null values.
