Another way of saying what he is saying is, it looks like you changed your training today before last week's training took place.
I am sure what time training occurs in Canada but in the USA it occurs fairly early Friday morning. If you change your training before training occurs Friday morning it will train for the previous week.
A good rule to follow, if you can, is wait until Sunday or Monday to change training in case training for some reason for the previous week is delayed on Friday.
