On the current master version, the sodium and potassium gates are not opening and closing when the action potential reaches the cross section. I suspect this is related to the recent conversion away from PropertySet, see https://github.com/phetsims/axon/issues/102.
Assigning to @Denz1994, since he did the conversion.
