Study mode PowerFlow Results showing "NaN" characters in Device details
Under certain circumstances, the Device Details panel, in the Power Flow Results tab shows "NaN" values instead of "0" for a substation with a "model Error" state.
Further analysis shown that the power flow results are "nan" due to a load on the feeder. All the attributes and profiles on that load point seem to be correct.
All strings should be readable
The issue can be reproduced at will with the following steps:
1. Find a circuit with 2 phase delta loads, in an island that is in model error status
2. Switch to study mode, and initialize to show real-time load conditions
3. Navigate to the 2-phase delta load and bring up power flow results.
Without fix: invalid and not-a-number symbols can be shown
With fix: zeros should be shown.
