Why does C2 not detect a margin calls for future strategy

Here is a trade ( apparently with live accounts on it). The worst drawdown is 400%+. How did the subscribers of this strategy not get liquidated and why doesn’t C2 show it as a margin call?

In theory, any strategy that gets margin called should have the trade flattened and the returns set to the actuals.

Stats shown by C2 give a very wrong picture.
