Simulation mode not giving concentration cost

[MytroGH]

So as I try to craft Malleable Pendant/Ring, as jc, and I try to use simulation mode, the concentration cost value doesn't give an answer, and instead it just says -nan(ind) regardless of what reagents I use in the simulation. This probably happens because the base recipe is t5 guaranteed, while using crests makes it a t3/t4
