Remarkable is that for f = x^4+1/(b)*(1/zzz) f is correctly translated to
Singular:
sage: K0=GF(11)
sage: #K0=QQ
sage: R0.=K0[]
sage: K.=K0.extension(b^5+4)
sage: R1.=K[]
sage: L=FractionField(R1)
sage: R.=L[]
sage: f=x^4+1/(b)*(1/zzz)
sage: f._singular_()
-1/(4*zzz)*b^4+x^4
That looks problem
Note that already
sage: (1/(b*zzz))._singular_()

That looks problematic, but is likely a
