I have a video from a few weeks back, which show how the list of trades (orders) was changed afterwards.
This is somewhat harder to make clear, but you will trust me that the two lines you see at n/a a few minutes earlier were filled with losses. This happened that day throughout.

If you did not pay attention while it was happening, you won’t have a clue about anything, but the losses where there and you won’t see them (like now, they are and remain just vanished).
