It sounds like the not showing street by street equity is a bug. Could you attach one such hand like this to a support ticket for us? That would help us considerably in figuring out what we need to do to fix it.
The way luck adjusted results are calculated is as follow:
For all hands which were all-in before the river where all players who called the all-in had known cards, assign to each player his equity at the time of the all in times the pot instead of his actual win or loss value.
