Structs and display2d

Structs are displayd quite differently depending on display2d. Is this a bug?

(%i25) display2d : true$

(%i26) gf_set(2, 4);
                                                              4
(%o26) gf_data(characteristic = 2, exponent = 4, reduction = x  + x + 1,
primitive = x, cardinality = 16, order = 15,
factors_of_order = [[3, 1], [5, 1]])
(%i27) display2d : false$

(%i28) gf_set(2, 4);

(%o28) gf_data(2,4,x^4+x+1,x,16,15,[[3,1],[5,1]])
