Mislabeled dialog in SpokenWOZ test set?

Taking a look at and listening to the test set you released on the website, I found that dialog `SNG0646` is completely mislabeled.
I assume this is a mixup of some sort since the annotations are completely wrong, to the point that using the speech start and end times from the annotation leads to empty speech sequences, which leads to errors down the line.
Can you confirm this? Was this also the case in the numbers you report on the website?
How should this dialog be dealt with when reporting results?
