I'm fairly sure the problem is that the defining polynomial for the relative extension is not monic. One solution would be to use an equivalent monic polynomial and keep track of a simple transformation allowing one to translate between the internal representation of elements on the one hand and print representations and conversions from polynomials on the other.
