Coupling Electric Circuits interface with Magnetostatics

Hello All,
I am trying to simulate a short circuit between 3phase conductors (3phase fault) in comsol.
1. I built a physical model with 3 cylindrical conductors and assigned them materials.
2. Next i use the magnetic fields interface to assign boundaries to my domain
3. I have then used Electric circuits interface to create a circuit with 3 sources to feed the single turn coil feature used in magnetic fields.
When i run my model for time domain study it gives me an error "The dependent variables comp1.cir.R1_i, comp1.cir.R2_i, comp1.cir.R3_i are missing in the segregated solver steps. Add them to existing or new steps. " I do not understand what it means. I tried to remove and alter my impedance value in the circuit. But it doesn't help. I have attached my model for reference.
If anyone can tell me what this error means or help my with any other ideas of implementing this it would be very helpful. Thank you in advance!
