Ideal Transformer does not allow for DC to pass

Hallo, everybody!

I am trying to use an ideal transformer (TF from Lumped Components) and I cannot understand why the DC current doesn’t flow through it. I also tried a very simple simulation, two DC constant current sources (1 mA each) supplying the two turns (primary and secondary) and, instead of obtaining 0 V across the inductors, I obtained 1 GV (obviously, this is a numerical error due to the impossibility of convergence). I also tried connecting resistors in series or in parallel with the turns, no success. Is this a bug of the ADS, or have I made an error? Thank you!
