NaN value in load flow (Specialized Power Systems)

Dear experts,

I have a power system (using Specialized Power Systems). When I do the load flow, the system converged, but the value of the load flow is NaN (please view the image). Did anyone meet this phenomenon? Is it normal?

Thank you in advance.
