For some reason the binding equations for the Complex parameters {{{V1.v}}} and {{{Z1.Z}}} were moved from the parameter binding equations to the equation section, which makes the model overdetermined and at the same time leaves the parameters without any binding equation, which is mandatory for parameters having {{{fixed = true}}}.
